I ordered a new prop for the BB, OJ 428 4 blade, 13x15.5 with a .090 cup. I want it to just tickle 5,000 rpm at WOT with a lightly loaded boat. That should be right at 50 mph if the engine has the grunt to turn it that fast.
We’ll see, standby for lake test.

I think you will be happy with that choice. My 13x13 OJ four blade runs smooth with lots of hole shot power and good top speed with good engine loading. I have two of them after bending one on a rock. OJ repaired it perfectly and I bought another to have a good spare.

I used your prop numbers adjusted for my under drive transmission to hopefully get close to the results you are getting.

New 13x15.5 4 blade OJ prop is a good fit, 5100 rpm with two men on board.
Still have a few items to get right on the boat. Bilge auto float switch wasn’t working and I still have a small but peski leak from the shaft log/hose fitting. I’m going to reroute the fuel vent line, it has a low spot collecting fuel.

Sounds great on the rpm. You have a beautiful boat. I'm confident you will sort out any issues.

Wide open at 48 mph in light chop, one section of windshield exploded. It was a real boating enhancer! Heather screamed, we cleaned up all the pellets of glass and kept boating. I was a little suspect of that section of glass, it never fit just right.

Wow! I had some safety glasses Crack due to being too tight of a fit on the Zip. I think tempered glass is better in framed windows, but I prefer laminated safety glass in open bracket mounts like we have. Hope you are all OK.

Roberta :shock:

It wasn’t a huge deal other than pellets of glass everywhere. So you are using laminated glass on your Torpedo?
I’ve had the exact glass and brackets on the Malahini for years with no problems. Weird.

I went with laminated safety glass with a tinted film in the centre.
Wasn’t cheap was about $450.00 but looks great and all good so far.

I had to wrestle with the section of glass that broke during installation. I will adjust my template for a better fit. I may hog out the side brackets to make room for a rubber gasket or bed the edge in a flexible caulking material.
Other than the glass exploding, I think all the significant bugs on the boat are worked out or have not yet identified themselves. 😁
Progress, not perfection.

I think the idea of tempered glass was to prevent heads from breaking through the windows and then backing out, resulting in severe lacerations when laminated glass was used. Tempered breaks in to pieces that are less harmful. But the shorter open frames most classic boats use will more likely allow safety glass to pop out.

All the classic frames should have channels sufficiently wide enough for the tarry gasket material. This stuff will bed the glass and insulate it from vibration. Any stress or strain on either type of glass will eventually cause it to fail. On the Zip, the glass was very close tolerance and heat expansion caused additional stress and a bumpy ride led to it cracking.

Yes, I am using laminated safety glass.

Aside from the windshield exploding, the new 13x15.5, 4 blade prop performed well. With 5 people on board it ran out at 5000 rpm.
