Prop Suggestions

[kingdavid]

Hey Greg,
have a 78 Spectra Daycruiser with a stock 350, thru the transom exhaust and a Mercruiser I/0.
Currently the prop is labeled 19.
I dont have a speedometer.

Seems like it is capable of more performance especially on the top end than what I am getting.

I do pull my boys on tubes, skis and waleboards so I dont want to loose the bottom end entirely.

Let me know what you think or if you need more info. to weigh in.

Thanks
Dave in Fresno Ca.

Really need more info to make an educated decision.

What is the outdrive ratio?

What is the current max rpm with your current 19" pitch prop?

What is the motors rated max rpm?

What is the current max speed (GPS)?

What is the speed (GPS) at 3000 rpm? (helps determine cruise efficiency).

Once that is known we can make some suggestions.
