350 RPM range

[altjimwilson]

I have a 350/Alpha on a 22 foot Larson.<br /><br />The motor runs about 3000-3400 at about 35MPH (on plane and timmed out).<br /><br />At full throttle this will run +4000RPM (not that I run full throttle much).<br /><br />Is this normal range for such a boat? I believe the prop is a 19 pitch.<br /><br />Thanks

Re: 350 RPM range

I haven't run a Chevy 350 in a boat before, but all the ones I've had in cars run perfectly in this RPM range. Unless you have reason to believe that there is a problem, you probably have about the right setup. Judging from the fact that you don't run full throttle much, I guess you aren't trying to squeeze out every ounce of performance. Go have fun with your boat and don't worry about the motor. It can handle it.

Re: 350 RPM range

A wot range of 4200 -4600 rpm's is what is recommended for the 350.
