Here's my 1987 175hp Merc Powerhead pushing my 23 WOT.

I bet you get closer to 45mph with the 200 yamaha

After having 2 different 200 hp on our Sceptre for a period of 8 years, I would predict around 37-38 mph at WOT. No way mid forties.

Bigshrimpin must be running nitrous O2....LOL!

A brilliant deduction! I'm gald we could help with your data mining and analysis. The gray motors are good ones - I'm sure you will be very happy with your decision. Glad we could help you get they'er.

That's funny Terry!!! I hated English class in high school, especially my senior year when the teacher's got more serious about my grades and less entertained with my goofing off, I really did not want to be their.

You did not help with squat...it's people like you that keep most people like me off of forums. If you have nothing good to contribute say nothing.

This place is a little different than those other sites. It's more of small town where all the people know everyone and they're business. You'll get a kick out of gofastsandman and spidercrab. Don't give up on it just yet...

Sorry, I just don't think an inline 4 cylinder is going to perform in real world conditions at any satisfactory level. 200 hp is pretty marginal for ponies on an offshore hull rated for 500 hp. Maybe a bay boat it is fine but you have to think about the torque needed to hold plane in seas and the overall requirements for load on a day offshore. Would it work... sure but it isn't going to be impressive at the least.

I get about 37-38 mph with my f225. I was wondering about the 200. I had a 225 ox 66 and it was faster than what I have now, but I couldn't wait to get it off the boat. My f225 isn't fast, but it gets me there. It's almost 11 years old now.
I think some folks are comparing apples and oranges here, 3700 rpms would maybe get me on a plane.
