20SF 130 or 150hpdi ?
 

I have to re-power a 74' 20SF; tossed between a 150hpdi and a 130 yamaha (both used). The extra weight of the 150 is what concerns me.. Is the extra 100 lbs. (approx) enogh to be concerned about?

Thanks,
Boni-B

Underway especially in the ocean the 6 would be a little nicer

If he still has the in floor drains, maybe you guys with this hull could chime in about whether it will make any difference in terms of water coming in at rest.

Re: 20SF 130 or 150hpdi ?
 

If thats the boat Im thinking of, I found a 97 Yam 200
pro-v in mint cond for 2700.00 that motor wieghs 418lbs
The hpdi is too heavy 470ish

Re: 20SF 130 or 150hpdi ?
 

that thing would scream

Re: 20SF 130 or 150hpdi ?
 

With an HPDI,You would have to move alot of stuff forward in order for it to self bail, even with no one in it.

Re: 20SF 130 or 150hpdi ?
 

I would think you can find the weight of the current motor and the Yammi Then stack that difference in weight on the cowling or whatever. It should give ya an idea at the dock. Assuming there is a current motor.

Re: 20SF 130 or 150hpdi ?
 

There's no power on the boat right now, so I have nothing to compare it to and the floor drains still go through the deck; recently replaced with bronze. I'm affraid to pick the hpdi and then find out she's sits too low.

Seafari, where is the 200, on LI? Wish the hpdi's wern't so much heavier than the carb'ed ones.

Re: 20SF 130 or 150hpdi ?
 

My setup has mine at the top of the bronze at rest. I really don't have any of the problems with weight and drainage and height that so many speak of. My motors only 410ish lbs. But 30" back. She would dolphin a little under 3200 in some conditions especially light on fuel, but the motor was not at the right height and there are no tabs. I love the simplicity of this boat! So I put an original cheap Stingray fin on and changed the motor height and gained 2 knts up top and I can't tell you how quick she pops you up on plane and now I can't make it porpoise. I'd like to get a blown 25" 175 60deg. Johnson/Evinrude to redo, super light reliable motor or an older non o-ring Merc. but really I want the OMC.

The extra weight of the 150 will not allow the boat to self bail. You WILL stand in water with that setup.

Re: 20SF 130 or 150hpdi ?
 

I have a 150 Evinrude on my 20SF. I cross the drainage lines & it keeps much of the water out.

Re: 20SF 130 or 150hpdi ?
 

My 225 efi Merc weighs in at 475 lbs and my 20 sf still self bails.

Re: 20SF 130 or 150hpdi ?
 

I had a 20 Sceptre with a carbed 200 Yamaha on a jack plate and it would self bail fine also.

Re: 20SF 130 or 150hpdi ?
 

I have a 20 with a 150 ox66 (precursor to the HPDI) and it self bails.

With that being said, it self bails for a couple of reasons:

1. Transom raised to 25"
2. Scuppers re-routed to go out the transom
3. 75gal fuel tank moved farther forward under the deck to balance the boat out (PRIMARY REASON)

Re: 20SF 130 or 150hpdi ?
 

My 20' Seafari had a Merc XR4 150, at 370lbs, and would self-bail with no one on the boat. Step on board, and water came up on the deck. Currently has a Merc Opti 90 hp at 375 lbs, ditto. I have drain plugs in the deck drains which I remove once underway, and replace before coming to rest. Unless I'm alone, in which case my shoes just get wet. :)

At rest, drains open, with me standing in front of the motor well, I have about 1/2" to 3/4" of water on the deck.

FTR, when I had twin V6 150 Johnson motors on the marina's '77 23' CC in 1983, it sat with about 3-4" of water on the deck.

My 20 has a 150 yamaha fourstroke on it and it still self bails

Re: 20SF 130 or 150hpdi ?
 

I will say if I get in the back of the boat to open a hatch to check batt. or bilge pump the drain on that side will fill slightly but nothing on the deck. Two people back there while not moving now thats another story. And when people see water coming in and on the deck I just tell them "All boats are sinking, some just faster than others!!" Non boaters look at you kinda funny when you say that, boaters just laugh and keep drinking beers. I would get the 150hpdi, a friend has one and its a great engine. Just my opinion

Re: 20SF 130 or 150hpdi ?
 

My 20SF with a saltwater 150 ETEC (433 lbs) I use plugs in my drains all the time. If I have to wash down some blood or fish slime, I bucket it in, pull the drains, and keep the boat in motion. Flows right out - them I plug them back up. Honestly, I have gone many all day trips and never pulled them. If I don't have them in, I too will have an inch or so of seawater on the aft deck.

Re: 20SF 130 or 150hpdi ?
 

That is what mine used to do nearly empty on fuel (<10 gals. approx.). I moved the battery under the console and added another to make it dual. I put them under the seat hatch in the console. Then I put a big old length of anchor chain in the locker under my anchor line. It's not bad at all, no worse than acceptible or the other couple 20's I go on from time to time and both have a light @400 6 cyl. It can be a PITA with almost any smaller boat that used thru bottom scuppers especially but how else would baby crabs climb in and chill out. It's fine because next year I am gonna put a schraeder valve on my bracket and fill it with 50lbs. of helium...j/k

Re: 20SF 130 or 150hpdi ?
 

If you put in enough, and add helium bladders under the deck, too, you can lift the hull to where it floats at the center V. You'll look like Fishjack's avatar all the time. That'll keep it self-bailing :D
