Looks good Steve. A lot of sharp edges though! Some kind of upholstered cover for the base would be pretty cool imo

I will keep a tourniquet on board instead. Cheaper.

I've got the same prop.. honestly didn't really notice much difference from the stock Yamaha aluminium prop. Let me know that you think.

Curious how the shockwave base is mounted? Are those like a lag screw/bolt? You can’t access under the floor for nuts I assume. Did you just kinda guess as to where to run them through? Did you hit a stringer or just the floor itself is sufficient? I have a similar floor and like what you’ve done there. Always scared of putting holes in my boat tho.

Thickest Lag screws possible screwed into the plywood and sika flex.

I got a SWS II with the SDS hub for my F300 and it spanked the factory prop I bought the boat with. It is now my close-second spare after a round of musical props that ended with a four blade recommended by a member of this site. I find the advantages of this hub to be as good as advertised.

I marked the holes cut a 4 inch hole reached in and used 1/4 inch plate aluminum backer as big washers placed the bolts sticking up through the floor using elastic bands bolt to bolt so they won’t fall back through. Placed bracket bolted on. The 4 inch Circle from the holesaw could easily be re epoxied in. Admittedly it was a real pain in the butt

Nice! I have no concerns about this ever coming out. It’s a sturdy base.

I meant more the sound with shifting, maybe the other one was just as quiet.. haven't owned many boats. As far as stats, I went from a 19p aluminium with a WOT of ~5600rpm, 30mph cruise at 4000 rpm. With a 17p stainless, cruise at 4000rpm went down to 26mph and WOT achieved almost 6000 but a couple mph slower.

Ok Steve you’ve convinced me I’ll buy it back. Hmmm same price?

I’m sure I’lll have to lower it a bit. After all it’s depreciated almost another year.

Your original 19P prop seems like a good match to your boat and motor. Going down to a 17P stainless 3-blade prop would just increase revs relative to speed as you have found. A stainless 4-blade 17P might be a better fit.

I kind of took a leap of faith a just bought it, as the Yamaha shops around here didn't seem to interested in letting me trying props out without buying it. I'd like to try a 4 blade

You could always watch the buy and sell sites for a suitable 4-blade stainless. This is how I acquired several of the props I tried. That way you don’t take a big hit when a new one doesn’t work out and you have to sell it.

Started my least favorite job today with the good stretch of weather forecast. 2nd time in 14 years. The glass panels still look mint underneath so that's good...
