motor size
 

What is the largest motor you can put on a v20 and still be safe with the transom??
:sand:

depends??? 2 stroke? 4 stroke?

I would say 200 2 stroke would be the max....but someone that used to be a member here had twin 125s I think...

someone will be along with a better memory than me...

so a 235 outboard would probably be too heavy for it

I've got an Evinrude 225 on a Gil Bracket on my V...

I have no idea why anyone wants to add these huge gas guzzling motors on a V20??
A 150 is all it needs with out all the weight on these old boats.

Unless you are on a fresh water lake you can't even use all the power on ocean water unless there is zero wind, Do yourself, your wallet, and the boat a favor and good with a nice 150 or something

Actually, the only reason I did it on my V is because I wanted to swap motors with what was on my Hydra... I didn't have a choice... Otherwise, I agree with MJ. A 150 seems to be the ideal.

Is there any laws that you know of stating that you can't have a 235 outboard on it?

Can't recall who, but somebody here was just talkin' about havin' a 235...that's a LOT of motor (weight!) for these hulls, but I gotta admit...I'd like to drop the hammer on one just to see what she'd do!!...

It depends on your particular hull..some models are rated for only 200 hp...but I'm pretty sure I've seen others rated for 235...

Going over the stated HP limit won't get you in trouble w/the law so much as your insurance company...they are reluctant to insure an over-powered boat...

What year model V20 do you have and is the ID Plate still readable?...

I have a 235 and it runs well but I am replacing it with a smaller motor. I almost didn't buy the boat because of it, but I wanted a V and I liked the hull. For what I do which is just fish it is way to much motor.

I'm assuming this 235 is an older pre-86 engine, if so it is barely a 200 by todays standards. The 235 was flywheel, NOT propshaft rated. The 235 became the XP when the 200/225 looper's came out in 86, and the 200 became a 175. The older 150-235's were all the same basic weight and engine size for the most part. There were 2 different bore sizes, and different porting through the years though. They all weigh in around 375-400 pounds and were cross-flow engines. They are also FUEL THIRSTY PIGS!!! The V-20 doesn't need the extra HP and could sure do without the weight back there. I'll have to disagree with MJ though about fuel economy of a 150 VS a 200/225. My 225 EVINRUDE(actually pushing a bit more) uses no more fuel than a 150 or 175 OMC or MERC on the same boat. The 150/175 YAMAHA though is another story. Some engines are more efficient than others at a given HP output.

I personally would pass on a 235 though as the fuel cost on that engine is pretty high, it EARNED it's name of 2 thirsty 5 rightfully. A 150/175 YAMAHA, 135/150 MERC 2.0L, or most of the large 4 cylinder 2 strokers provide decent economy with lower weight. The newer 150/175 looper OMC's are GREAT engines, but are known as thirsty.
