Q1: what is a good choice for a propeller on a SUZUKI DF175 for powering a 1973 OUTRAGE 19 [that has been modified by removing the upper cap to create a "low-profile" boat of reduced weight]?

[Moderator's note: a second question in which a survey was proposed has been deleted. Please to not propose survey questions. If you need an answer to a question, just ask the question, and do not create a survey to poll readers to see if they know the answer.]


BACKSTORY
The 1973 OUTRAGE 17 was previously powered by a Yamaha 150-HP engine using two-stroke-power-cycle design.

My performance preference is to have [better acceleration at full throttle from a standing stop] instead of aiming for maximum full-throttle boat speed.

[Moderator's note: thread has been moved to PERFORMANCE. The PERFORMANCE forum discusses boat performance and its optimization, particularly propeller choices for specific boat and engine combinations.]

A propeller recommendation can be given if you supply more information.

Q2: what will be the total boat weight including the new engine and allowing for the low-profile modification?

Q3: what is the gear ratio of the DF175 engine?

Q4: what is the manufacturer's recommended full-throttle engine speed range in RPM?

Q5: what is the maximum propeller diameter that can be used on the SUZUKI DF175 engine?
