I am going to be putting a new to me engine on my cobra 188 this week. I am putting a 200 hp Yamaha pro-v. Any advice on what height to start with on the engine. It has a 25 pitch tempest on it now. I have a manual jack-plate, but just looking for a good starting point. Thanks in advance for any help. I am excited to wake this boat up a little, I am upgrading from an older 150hp evinrude. Any guesses to what speeds I should be able to reach.
I'd love to have 200 on mine. I'd start by running the new motor where the old one was/is and go from there keeping an eye on the water pressure and RPM.

Should run close to 70 imo.

should run around 70 for sure. What speed were you getting out of the 150?
Fastest I got out of the 150 was 59.8.
That's about the best I've seen with my boat empty too. 56 -57 is what I get carrying around my fat butt and tackle store.Originally Posted by cdoz35
