i'm going to use this as my hello post. back in 2005 i purchased a wellcraft 220 sportsman with a yamaha 225 hp 4/s on the transom. this is where the problems began, the boat always felt heavy and under powerd. played with diffrent props and trim settings to no avail so i just lived with it. untill this year i fell victim to the exhaust corrosion that was the final straw. this slug like peice of rust is being replaced by a 250 hp gen 2 etec as i type this post. this purchase was not made blindly i did a lot of research on this product from weight to torque ratings to warranty. even though this motor is as heavy as the 4/s the torque rating and duration that it is supplied is twice as much. plus i don't have to screw around with a steering ram or a stupid primer bulb. i am also running a g2 250 on a 2015 wellcraft 220 fisherman that was built with that engine optioned for that platform. the differance between the two boats is amazing. i wish these were available in 2005. the repower gets water tested tomorrow and returned to me on friday. i will be on a test prop till mine comes in. i can't say enough good things about chambliss marine. more to come
A 250 HP G2 will make your boat come alive compared to the older F225. It can run mounted higher on the transom and either an RX4 or a Rebel prop would work well for that rig. Prop it for an average load close to 5600-5800 rpm.
had a chance to do full tests on flat water the test prop yeilds me 43 mph @ 5360 rpm. so still more dialing in to do. over all i love this motor/boat combo now. it has so much power and torque but yet is verry controlable. updates to come once new prop is on.
It sounds like it will be a great rig.
What size and model was the test prop that got 5360 rpm and what size did they order?
it was a 3 blade rebel. joe said he was going to talk to someone at corporate and get thier input on the new size. i understand this because i am probally the first one to re power a boat like this model. again joe did a great job and i am verry happy with this engine on my boat.
If possible, also try an RX-4 prop as it really performs well on a variety of hulls.
