How much power can it handle?

[ericrn]

How do I figure out how much motor my old boat can handle? It's a 1969 V191, I currently have an old 175 merc that is more than a little fussy. I would like to look at a new motor but how much weight is too much? I would like a 225...Am I dreamin?!

I was gonna say that was too much weight......but given the history of your boat, I'd say that it would be OK. I wouldn't do it for the same reason though......

THAT BOAT NEEDS TWINS!!!!!!!!!!!!!

A new 225 is only about 500lbs, the old stacks were about 300 each, so the 225 would be lighter than the old twins.

as long as the transom is solid i would think you could run a 2.4 on it. they are just shy of 400# i think. pick up a later one that runs good for $2500.

I would think you could run a 2.4 on it just don't hammer it. Remember the twins that were on it were only producing about a 175hp between them. All the old V-6's weighed about the same so pick your hp and be careful with it.

That thing needs a E-tec 250 H.O.

there are 150's all over ebay right now for 1500 bucks.

E-tec 250 H.O

That thing needs a E-tec 250 H.O.

How does the E-tec 250 H.O run?(specifically on a Pulsare 21!)

Same as on a V191...a ton of money!!

Great Mota'...but nothin' on E-bay....

If your transom is solid then you do not have ANY reason to limit yourself anymore than some of the new boats and their motor and their set-up. I've seen Checkmates rigged w/engines that were far over their designed max HP ratings by todays stds on boats that were built in the 60's and 70's. A 72 15' MX-15 w/ a 150hp??? ( I blew mine over... but I stuck a trim button) Your boat then can handle a 2.4 245 hp or 2.5 260 hp or a 280 hp . Even the 3.0 liter Merc 225 was only 440 lbs. Great motor..Stock!!

If you want to get a high-performance motor great. But there are basic good solid motors from Yamaha and OMC too that will do the job and your rig will handle them. I wouldn't go to ,however, into a four-stroke under any circumstance as that's when you WILL have a weight ( and performance )issue.

This Predictor is a little funky to drive at WOT. It took alot of seat time to grow the nutz
to fly this one, but at 60 or 70... not a problem!
