Here is what the back of the prop looks like. I didn't know the thrust washer comes off. Looks like it may be slipping but can't tell if it is melted hub rubber or just old grease balled up. Picking up a new 4 blade 21 pitch tomorrow.
Tach adjustment worked, cut RPMs in half. So there should be a ton more throttle left and will get it on plane this weekend and test with and without the transducer in the way to see if it is causing cavitation although it is off to one side of the prop (see pic)

That shot from the back looks good. Change the prop like you were thinking....leave the 'ducer as it sits for now, it looks a whole lot different from this angle. May be that froth was coming from the 200 set a little too high as Nando alluded to.

Anyway...when you go run her....let the big dog eat :mrgreen:  Throw her down straight out of the hole and see what you've got :thumright:

Maybe my good glass eye talking but that hub looks toasted to me.

Did it smell really bad, aka burnt rubber?

Good luck.

My 2 cents - rehub that prop (relatively cheap) and run it.  First, you will see if a spun prop is the source of your high rpm/low mph issue (most likely culprit IMO).  Second, you can judge the performance with a known wheel size and pitch, and thus make the process of selecting the best match prop much easier.

The hub on the old prop doesn't smell like burnt rubber and my local prop guy couldn't tell if these are balled up pieces of rubber from the hub or just grease balls.
I bought a new 4 blade 21 pitch and I can swap it out for another size for free. It's a bit of a hassle because I have to drive 30 minutes to get to the prop guy and he is closed on weekends. So I will test the 21 this weekend and then report back and see if another size may give better performance.
Old prop will be kept as a spare. Prop guy said he doesn't think it's spun or I wouldn't make it over 10mph usually and I was at a consistent 18mph at 6000 RPM (actually 3000 RPM).

Tested the new 4 blade 21 pitch prop. Old prop was definitely spun and needs a rehub. Now running a consistent 30MPH at 3200RPM with 3 big guys, ice, full gas tank, and gear. Is that about normal for these hulls? Or what should I be aiming for?

Engine and new throttle cables still need some adjustment but anything over 30MPH and the hull started to bounce due to the waves so wasn't able to see WOT speeds. 12hr day 18 miles off shore and boat performed flawlessly with a nice dry ride.

Can't get the engine timing figured out though. Tried to match the dwell and advance to meet the settings listed in the factory manual but adjustment of the timer base and idle screws is a bit confusing. Time to take it to a pro I guess.

Cruise RPM seems a little low. Hard to tell if you will be able to get to 5000 and above at WOT. I tried a 4 blade and could not get above 4500 rpms. If you can't get it above 5000 you are putting too much load on the motor and making it lug, even though the holeshot is great.

I agree. If you can't reach the low to mid 5000's on that motor then it's too much prop. You will start fouling plugs if the motor has to constantly work too hard as well as compromise fuel efficiency

Probably couldn't get more RPM because my throttle cable wasn't reaching the full extension on the lever at the motor. I have been adjusting the cable screw each time out to get more throw but then it sets the idle higher at the same time because it doesn't return all of the way in the opposite direction.

Hole shot wasn't great and I really don't need it to be super fast, would rather have better fuel economy. Would you suggest a 21 pitch 3 blade instead?

It planed nicely and is balanced well with the bow always down but what do you guys think of the bolt on hydrofoils?

I ended up with a 3 blade 19 pitch that hooks up hard, cruises nice at 30 at 4000. WOT is 5500 to 5600. Don't put the fin on yet, try to remedy problems with prop first. Tabs are a better idea rather than the fin.

Ok perfect. Picking up a 4 blade 19 pitch tomorrow for testing Thursday then maybe 3 blade 18 or 19 this weekend. Hopefully can get it dialed in. Will hold off on fin install too, one issue at a time.

IMO the three blade will make the boat porpoise more. I recommend a stern lifting four blade with either a 19 or 17 pitch.

Also, did you move the fuel tank forward to offset the setback of the motor?  If not you're going to need trim tabs to go along with the stern lifting prop.

Boat doesn't seem to porpoise at all. Only reason I think I was getting some bounce at 30mph was the swell in the ocean. Heard the prop come out of the water on a few of the big rollers and also landed pretty rough on those so backed off the throttle a bit.
I did move the gas tank and console forward 18 inches in my build as well as having 3 group 31 batteries inside the console and a 72 quart cooler seat in front of the console.

Will report back Thurs eve after the test of the 4 blade 19 pitch
