Default Update on my prop -- added a doel fin... HUGE improvement!

Thank you @thefermanator, here's the latest updated...

I added doel fin to the outboard, and WOW! I now top out at 35 MPH, and can spin the prop up to 6200 easily. That's a HUGE difference, and now the bow stays down a lot more even without using the trim tabs!

In other words, I think that this suzuki 14in x 17 pitch stainless steel prop is a great match for my boat.

My next question is about engine height. The prop shaft is currently mounted in the middle hole, which puts the shaft approx 8 inches below the bottom of the boat.

Any feedback on what height is ideal? I'm thinking that the motor should be higher, but don't exactly know, since my prior experience is with 20" motors on fresh water lake boats.

I'll also try searching the forum for any previous posts on this topic.

Thanks!
