Tom, great minds think alike. Now you can put your snack on top and it won't slide off so easily.

Here we go. Just gotta take everything back apart, sand, and polyurethane. I've also used every bit of wire that I had hooking everything up. It's amazing how much wiring there is in a boat this size.

when I bought marine wire,I got spools of the different sizes(some I haven't used yet)Might have build another boat to use it all :lol: it's challenging trying to route it all so it doesn't show.

I'm going to try a four-blade prop. Mainly hoping to eliminate cavitation in tight turns. The new prop rings like a bell, which seems indicative of the casting quality.

Let us know how it performs. I have to be trimmed all the way in for a tight turn on plane or prop sucks air.

Same here. I'm going for a test run tomorrow.

The new prop seems to be a winner. The boat is way easier to control in just about every way. I don't have to be trimmed all the way down for turns. The cavitation problems are pretty much gone now. It is a Turning Point Hustler 13x17. I am thinking I will trade it in for a 13x19 as I am hitting about 5800 RPMs at WOT and I lost a couple of MPH at the top end. I think I'll get some back going to the 19 as that is the pitch of my old prop. Turning Point recommends not changing pitch but I did anyway.

Matt, this might eliminate the need for those trim tabs. I have way more control trim wise.

Glad you’re pleased with the prop. I’m running a 13.25 diameter x 15 pitch, 3 blade stainless. 5400 rpm is the top with a light boat. I just don’t think my 3 cylinder 90 has the grunt that your 4 cylinder does.
Most importantly, you were on the water in a boat you built from a few pieces of paper that came rolled up in a tube.

Mine is a 3 cylinder as well. Evinrude says 5000-5500 full throttle range. So I probably shouldn't be winging it up to 5800. I'll go up a size.

It was a fun cruise on the lake. A lot of people waving and asking questions at the ramp. I also got a chance to really break in the new speakers.

I didn’t know Etec 90 hp are a 3 cylinder, cool.

There is a 90 H.O. that is a 4 cylinder. It is a detuned 115. There is a 70 lb weight penalty.

I went from a 3 blade to a 4 blade power prop on mine and it improved my hole shot. I don’t have any problem with cavitation, but I have my motor set just a bit lower.
