Power for 20 Master Angler
 

Greetings Gents,

I have the opportunity to buy a 115 HP Suzuki 4 Four Stroke at a good price. Its a long shaft motor which will accomodate my plans to raise the stock transom to 25 inches.

I've read the 20's have decent performance with the 115's. I'm not looking for the boat to be a speed demo, I'm merely looking for a decent early 20 knots cruise speed. My main goal is fuel efficiency reliability.

I plan to put a T-Top on the boat and I understand the performance will suffer, but I'm wondering just how much. Bottom line question is will a 115 Zuki push a 20 Master Angler with T-Top.

Thanks
-Alex

I run a 140 Suzuki on my 20 SF, and have run one with a 115, there is little difference. A 20MA with a t-top and Suzuki 115 4S will not be a speed demon but it will be enough and it will be very efficent to boot. There is a member who has a 20MA with a Suzuki 115, he lives in CT but I do not remember his name. I do know he loves the boat / power combo.

good luck

yes.

Re: Power for 20 Master Angler
 

Thanks for the replies guys. I'll be on the phone with this gentleman tonight. The motor is out of state, so that may present a little challenge...but if I can get a good deal....I'm going for the motor.

I was a little concerned, but as you guys suggest I don't think there will be any significant issues....it won't be a speed demon, but honestly speaking in most fishing conditions you rarely run at the speeds a boat is capable of...Id rather be efficient and reliable.

If I want a speed boat, I'll restore a little Formula/Donzi/Cigarette type deal and power it with a 496HO :D lol

Thanks guys...off to continue work on my project.

If I was buying a motor that would not be even a choice unless its almost free, 1st 4S are not as peppy as 2S in the same HP. Second that boat really needs at least 150, when the came out the inline Merc was the choice, but a 175 would be better. Will not get any gas mileage with it all all, if thats why you are thinking 4S, it will have to be nearly WOT all the time and that will kill it. My guess on that you could use a carbed 150-175 and do as well due to reduced throttle. I also think the extra power will help the boat ride much better, just my opinion but want to see you happy. The MA I just bought has a 200 and is way more than needed, see Schnoors post on 4S compared to 225 2S

Re: Power for 20 Master Angler
 

at least a 150?

As mentioned before one member has one with a Suzuki 115 and is thrilled and another has a 130 Honda and I have not heard him complain.

Re: Power for 20 Master Angler
 

No way that boat needs "at least a 150". I'm running a 20' Seafari, which is a little heavier than the CC, and taller, with cabin and windshield, with an older 115 Johnson. If I read the original post correctly, he's not concerned about top speed, wants a low 20's cruise.

Mine with the 115 cruises easily at 24-25 mph on gps, tops out in low 30's. Generally, open sea conditions up here on the North Shore limit my cruise, anyways, I'm often happy to just plod along at 20 mph, and damned glad of the Sea Craft hull and it's sea-keeping capabilities. For my money, at most, I'd go to a 4 cylinder 135 / 140, but would not go up the 2 more cylinders, and added weight, to get to a 150 or above.

But that's just my .02 worth.

Blues - Hows the fuel economy with that motor?

Re: Power for 20 Master Angler
 

Big - I can't give you exact numbers, just got the boat last year, by the time I fixed the transom, got it in the water in August, and ran it till the stripers and blues left in mid October, pretty much every weekend - but I have the 47 gal tank, filled it up once, ran it for 8 hours+, chasin fish all over north of Cape Anne, still showed better than 1/2 tank at the end of the day, went out the next weekend without adding any, ran out, trolled around for 4 hours or so, and back in, still showing 1/4 tank - never put in more than 18 gal. for a days trip after that.

They say the old carb motors are gas pigs, and maybe so, certainly my earlier experiences with 2 stroke outboards was that they were gas hogs, but this is a pretty economical, and capable, rig, in my view.

Re: Power for 20 Master Angler
 

I've heard the numbers for the 115 Suzy are very close to those of the 140. While not the same engine, my fuel consumption with the Suzy 140 and a full 75 gallon tank:

30mph cruise, 4000rpm (WOT is 6K), 5.7 gph according to the Floscan.

I think the real numbers are actually just a little bit better than that as the Floscan said I'd burned 61 gallons of fuel but it only took 58 to fill it up the other day. At any rate, I'm covering more than five miles for every $3.50 gallon of gas.

Re: Power for 20 Master Angler
 

Just my opinion, I had a 115 on my 18 and it was OK but we are talking a 20 MA with a T Top and I personally think it needs more power. Will it get on plane and run sure, just think it would handle much better with more power, top speed is not the reason I say it will handle better. You want the boat getting up on the deeper deadrise of the hull for cruising speed, plus if your cruise RPM is 4800 vs 3800 it will use more fuel, with a 4S that would be offset but thats not why you pay extra for 4S.

Re: Power for 20 Master Angler
 

I have a 20 SF with an older 130 Yamaha 2S and this is plenty of power for the hull. I had an old Merc 150 on my last hull, and it went about 44 mph; the new boat does just over 40 mph (38 knots). The T top will add weight and drag, but it should be okay with the 115. There is a guy here in Britsol that runs a 20 SF with a Yam 90 and he has no problems, even though he loads it up and uses it as a ferry to Hog Island.

I think for these hulls, the bigger issue is that you do not want the weight of a 6 cyl engine on the back. I think the ride is much better with the 4 cyl, and the Suzy is a light motor, probably very similar to my 96 Yam.

Re: Power for 20 Master Angler
 

Theres a Yammi 115 master angler near me. He said its no speed demon but it gets up and goes, there are quite a few 20' SF's up here to with 115 Suzis on them.

Re: Power for 20 Master Angler
 

Thanks for the responses guys. I'll be looking at engines from the 115 to 140ish range. I've actually been looking at the Evinrude Etecs.

Re: Power for 20 Master Angler
 

From what I hear they are awesome and very competitive in every aspect to 4s except much less weight/HP ratio. Only some minor issues usually due to rigging issues, I guess all the new motors are a tad finiky on the initial set up.

Re: Power for 20 Master Angler
 

Alex,

I am repowering my 76 20'MA. I am removing an old Evinrude 235 and replacing with a new 175 hp E-Tec. I will let you know the performance in a month or so.

Re: Power for 20 Master Angler
 

Hang on tight :D that will be a serious upgrade

Re: Power for 20 Master Angler
 

Thats some serious power! I was looking at the 115 and 150 for my boat. When I spoke to the Evinrude dealer he said he would rig the motor for an additional $ 700 bucks and that included everything.

I've decided against buying a used outboard. I did it before and I had nothing but trouble since. Besides I'm taking my time and doing a very thorough and nice job on my boat, so If I get a good deal why not treat myself to a new motor.

Re: Power for 20 Master Angler
 

thats what you should buy quite frankly, perfect power for it

Here's some a link to my project for anybody whose wondering!

Re: Power for 20 Master Angler
 

Ouzo runs a 140 Suzuki 4 stroke on his 20' Seafari and it is a nice setup. We've gone out and fished all day for 12 hours and only burned about 30 gallons.

Considering that his Seafari is heavier than the MA, and filled with a lot more stuff, I think you would be fine with the 115.

If worse comes to worse, you can always add NITROUS. :D

I would have to agree with Eggsuckindog on the 150hp VS 115. I just repowered my 20MA with a yamaha 150. I use to have a 200hp johnson. And given what you are going to add, that adds a lot of drag, and if any other adults join you on the boat...! Egg- is right you will have to keep it nearly WOT. and you know that's not too good for the life of the engine! I'm no speed demo either, but i tell you it helps to have that extra power when you need it most. And with a 150hp you can back down on the throtle and conserve fuel that way. I totally agree with EGG.
Think real hard!

good luck !

Re: Power for 20 Master Angler
 

20' MA Heavy Hull 150 - 200 Had em' both & could'nt imagine havig less than a 150.
Scream'n reels' :cool:

Re: Power for 20 Master Angler
 

I agree with brad too. I had a 1999 150 ficht on my 20MA for a little while before I hawked the motor. It would top out at 40 mph. I'm sure I could have squeezed a few more MPH's out of that POS motor, but I could never get it to run right.

Re: Power for 20 Master Angler
 

here were csnick's numbers with the 140 on a safari with a hardtop.

2K, 6mph, 1gph
3K, 11mph, 3gph
4K, 23mph, 5gph
5K, 30mph, 8gph
5.8K, 36mph, 10gph, WOT
