Re: RPM question
btw all floatation has been cut out so boat isn't waterlogged and no hooks in the bottom

Re: RPM question
I'd want to be in the 3800 range with a load, you can run it up around 4K light and 42-4300ish on the governor. You probably need tuning and maybe a prop change to get you there.

Re: RPM question
I put one of PVT rev kits in my 23 gdlt and set oow rpms at 44-4500, I also ran a BBlades 9x7 prop with decent results.

Re: RPM question
I need to call B&S with my engine info, 18hp Vanguard, and find out what RPM's the motor is supposed to turn. Installed new shaft , seals, prop last year but haven't had the opportunity to run it on a boat, but that is going to happen shortly. Tach shows 3700 Rpm's with no load, and reading here that looks like it might need to be tweaked a little. Looking for opinions from folks, thanks. FYI, I installed the GoDevil factory prop, I believe 9x4.
