Best choice for repowering 20' MA
 

Trying to decide what I should look for but all I am getting is more confused. If you have seen my project thread, you now that I am in the process of enclosing the transom and already have a bracket w swim platform to hang on the back.

With all of my heart attack bills, the new budget is tight and I refuse to strap myself with a motor payment. I had a buddy that was going to give me an older Evinrude but that fell through. As such, I am strictly looking for a used engine.

My confusion is what type of previously loved engine should I look for? I don't want to hang too much weight on the back nor do I need/want a rocket-ship. Used Etec's are hard to come by which leads me to think that people simply don't sell them. I have seen a few 115hp Etec's but not sure if that would leave me under-powered. The only 140hp Suzuki 4-stroke motors I am seeing are from 2002-2004. Are those as good as the newer Suzukis?

What engine do you guys think combines the best price/power/weight balance for a 20' Master Angler with a bracket? Lastly, I would also like something a little bit quieter than say my 1992 3.0L Mercury 225 was on the back of my 20' Sailfish. That thing was a screamer but dang was it LOUD.


HELP!

I understand your dilemma, and have enjoyed your build. My MA has a 175 looper, and to be honest, I haven’t heard her run under a load in a few years. 375 pounds IIRC. It’s awesome power to weight with the 70 gallon fuel option.

My 20 Seafari has a 150 Etec, which I LOVE. All the torque, damn close to as quiet a Yammi 4 stroke, and way more fuel efficient. If she crapped the bed, I’d be looking 175-200 Etec, but I understand the financing issue. Beautiful boat. Best of luck however she is powered.

Just happened to see this because I know the owner. Not sure what your budget is.

thanks for sharing but need to spend about 1/2 that or maybe even less if I can. Although that does seem like an awesome deal for someone.

There were some corrosion issues with early zuke 140's I have I think an O6 on my 20 and its a great motor. The new kid on the block to look at is the new merc 115

I'll vouch for that!

Is 115 hp enough for a MA with a bracket?

As far as weight goes, what is the heaviest I should consider? I know that she will not be self bailing and already have a monster bilge pump plus another pump on the deck as the previous owner used to plug the deck drains and used the pump on the deck to purge the water.

You would be the first to put one on a 20 MA with a bracket. Have a zuke 140 on a 20 sceptre (with flotation bracket) standard deck. Routed the scuppers out the transom put on Flow-Max Ball Scuppers and they work fine. I really think the HP/ motor choice is a very personal decision..some guys are fine just putting around and some want the haul butt. I had a 130 Yamaha on my old 20 SF with bracket and it did very well with 2 people.

Avoid the 02-04 140 Suzuki. Those model years had metal casting plugs put into the aluminum engine holder and were very bad about corroding at that point. The fix is almost impossible. All newer years are fine.

A 115 ETEC would be plenty. Terry England of CC has a 25 bertram with twin 115ETECs that runs great. It is about three times as heavy, a lot wider and deeper than a twenty. I had a Seafari 20 with a 150 Black Max that was much faster than I needed offshore. More than plenty of power even with 3 divers, 10 tanks, extra fuel and several hundred lbs of ice and fish.

With a bracket, any engine will be hard to zero in for low speed planing. You will probably have to experiment with props. See Bushwackers posts for the best insight.

Good luck with it!

Excellent advice here.

These hulls are far more efficient than the formula derivatives.

I have an eagle series 60 degree omc 150 on the transom of my `89 20.
She would not plane under 18 with different stern lifting props.

I put a new tank in last summer and moved it forward.

I also changed the angle of the new coffin I glassed up to hold her.
I had real problems filling the tank because of the angle before.
More weight aft and I had no idea. Now she sits on her lines.

I struggled to maintain plane at 3k rpm.

Now I can hold hard at 2500k with ease and she is sooooo happy.
12 mph. When your hull is wet, she will not pound.

When you go airborne, you will pound.

There is a lot to think about here.

There one on the Facebook page running a proxs 115.

My family has a 140 Zuke on an 18 sf. I have had a 130 yamaha on 2 different 18sfs and also had a 150 Johnson on an 18sf. The 130 Yamaha would be the lowest cost to use and the best weight to power ratio, 150 etec would be my 2nd choice due to the power -Vezo has one on his 20 Seafari, 3rd would be 140 Zuke due to reliability and efficiency, and last would be the 115 etec because I think you want more power.

Have the Jedi’s and David Copperfield been notified about the magical 12 mph planing ability?? Congrats Sandy. The CSC Bible is never wrong.....

Found a really good deal on a 2009 evinrude 130 etec. I have heard the new 135HO is darn good on these hulls. Since this is only 5HP less what do you guys think? Can get the motor and rigging for about 2 grand. Owner is fine with running it on the stand for me and letting me check compression

That 135 HO Etec is a detuned 150… I would grab that if you can.

Sorry, that was a typo. Fixed it. The engine is a 2009 130.

What Snookerd said, "I would grab that if you can" ! Especially if it has good compression on all cylinders and clean. $2,000 seems like a good price. Good luck!!

The 130 etec is still a great motor. The exhaust system has a mechanical tuning feature to give it the extra 15 hp from the 115. I have read that component can get stuck open or closed.

The four stroke 2.1L 115 Mercs (Either the Command Thrust or the ProXS) weigh in around 360lbs which is very close to the weight of a two stroke yamaha 130. They both put out more than 115hp. They are mini versions of the Merc 150 3.0L 4 stroke design.

In all fairness, I think my gps is set to kts.

I kinda fell into this Danny.

I changed my prop to on ole SST 1 15 x 16p.

I remembered the discussion w 76Redseacraft years ago.

The exhaust gate you speak of is called the rave on Ski Doos.

Remember, pipes and chambers on the old RD 350s and 400`s would wake
up but you could only tune for high or low end HP. The rave gate closes at low rpm
and opens on the high rpm step.

The SST1 has an exhaust diffuser ring design that I`ve not seen on other designs.
I feel this is the magic bullet. The HP bell curve in my factory manual
shows max at 5k. Above that you are just over spinning the engine.

I had the prop collecting dust and just changed it out for the west coast bent prop
award. I brought the trophy, but nobody grounded out, so no award was presented.

The prop just feels so good and linear. I`ve tried a bunch of props over the years.
It is also light and shifting was much improved as far as my clutch dogs sounded.

No heavy clunk like the 10+ lb props.

Nice Sandy. Knots not mph...12 is magic. Sounds like a winner with that prop.

The 130 ho is not a detuned 150...its a hoped up 115. The 150 is a v-6 and the 115 and 130ho are v-4's I have a 115 and have had no problems with the exhaust valve getting stuck. I have replaced one stuck valve over the years of working on evinrudes, and thats because it had a ton of hours at idle, and not useing xd-100 oil.

My 23 will slow down and hold 12 - 13 mph in any sea. This particular day was calm. Torque curve of the Merc 150 peaks at 3000rpm.

Topflitegraphics edited his post after he caught his typo saying it was a 135HO. The 135HO is a detuned 150, you missed his original posting because it was edited. He first thought it was a 135HO. The DIFFERENT exhaust valve in the 130 is also on the 115HO. If you have one of those motors or have experience on those, that is good to know you have only seen one. If you have a regular 115, then you wouldn’t be dealing with the same configuration.

Tim-Nice!! That’s what I’m talking about! Sandy was just saying his setting were on knots....My Zuke DF 300 transom mounted planes at 12 knots. I was referencing a post where Kmoose did not think that we could plane at that speed in a 23. See below....

That's some classic Moose!!

Moose on pics of the ole 21 next to his 23.

I call this pic 21 My Ass!

Well, going to do my best to get the Etec. Hopefully, he will still have it after the holiday weekend

Good luck, Bro. You’ll be very happy with it!

Good choice

Solid motor. Hope you get it.

I may have missed it, did you get the eTec??

Here's one I just saw that might be open to an offer, however the eTec is a really good deal.

http://mbgforum.com/topic/8308-1996-...#comment-67595

Haven't gotten the Etec yet. The seller could not meet up with me until this weekend (hopefully some of my customers pay me so that I have the cash by then).

Back at it again - had to take time off from the boat to take care of other things. The 130 Etec ended up being a total turd. Needed WAY too much work.

Considering the following:

2003 Yamaha 150 HPDi with 461 hours - asking $3650

or
1998 Yamaha 175 SWSii OX66 Unknown hours asking $2500

or

1996 Yamaha 130SWS owner asking $2500

also

2004 Suzuki 140 4S w about 350 hrs - asking $3500

Thoughts?

For etec, try ARG Marine, FLA, top notch - no junk, will warranty and ship in crate.
I bought from them. On web site - ask for Victor, they sell a lot of motors.

The OX66......really old tech, lots of fuel and oil burn.

Better if you can get a newer used technology.

Old tech does not really bother me. I figure this is just going to be a 1 or 2 season thing for me while I squirrel away some cash for a new 140 4-Stroke... I did not boat at all last summer with the old motor crapping out, transom needing to be redone, buying a house and then having a heart attack. Given all of that, I REALLY want to get out on the water this summer!

Stay away from the HPDI.
I'd go for the OX66 way before the HPDI.
Although, a 175 OX66 seems like a bit too much motor for a 20. :confused:

didn't the 04 Suzuki have corrosion issues? If not, then that would be my pick.
