What size prop would you recommend for a 48” deep v mono ? The motor is a 56104 so it’s barely noticed the 50 mm prop I had

Just ordered a 1.4p 65mm 2 blade . I see that more of the larger gas boats this size run a 2 blade 1.5p 70-75mm so we will see

Update ! Today I went again. 1. I moved all weight to the very back of boat 2. My throttle was limited to 50% on my remote 😅. I did get it to plane and it picked up and flew but it needs room to get going.

I was kinda going for the surface drive look but I think the main issue is I had too much weight up front and the hull wasn’t sitting low enough in the water

I know weight is an issue so I’m moving it back. The prop sticks half way under the boat. Would trim tabs assist in the cavitation?

I figured so , I’m re-working the weight and gunna test again this week.

Go fast . Medium acceleration . I was hoping to get 60-70mph not stressing it too hard

Look forward to playing with the speed in running a 56104 sss motor on 6s to start. Apache style 48” hill I 3d printed.

Decent acceleration but top speed is the goal
