400 with 1.76 transmission prop choices

[Moombas]

Thanks for the reassurance, just spoke with Jim, 3591 inbound and sending my 3407 back because I was surfing at 4400 rpm which was awful.

Now I have talked to 4 Moomba owners that have no prop burn with 16" props.

3591 is a great prop. Your RPM's will be much lower than 4400

This prop rocks so far, I was able to add some lead back for a total of 800lbs of lead + my 5,500 lbs of water ballast. I am holding speed either side at around 9* pitch the wave is amazing. I can surf at 11.2-11.8 RPM always under 4,000 now. I also got the prop from ACME but ordered a 3591B (blem) for under $700. The reason I like the B props is it usually just means they were installed and tested and then returned. It also allows you to exchange them until you find the right prop.

I do think This is pretty much the edge of the weight limit for this boat with the 400 if you are trying to achieve that 9-9.5* pitch which seems to be the general consensus for the best wave. If you bring the pitch down to 8 you could run more weight no problem, but the wave won't necessarily be better.

Great to hear you are getting dialed in !!

Looking forward to getting out and finding the limit myself this year !!
