It is a viper but I'm not 100% sure on the pitch. I tried it out again today. It was pretty rough in the bay so I didn't really pay attention to any numbers.

At one point I backed it down to about 20 mph and that's when I missed the 4 blade. It seems like my boat was dryer and handled rough conditions better with the 4b.

I think I'm going to just order a 4b x 15 and call it a day?

On the BRP props, I think the Viper is a high speed prop that most of the dealers seem to be pushing, but for a 3B prop, the Rebel has a lot more blade area and acts somewhat like a 4B with lots of stern lift, sort of like the Merc Mirage. I tried a 15.25 X 17P Mirage 3+, but it wasn't as good as my 4B 14.125 x 20 Apollo, and I couldn't reach optimum rpm with either one at max load. My 15x15 4B PowerTech is a better heavy load prop than either of them. Would like to try a 15P Rebel, but it supposedly has very low slippage and acts like it has more pitch than advertised, so not sure I could turn it to optimum RPM.

I dont understand how you can turn a 4B 14.125 x 20 and I cant turn 4B 14.5 x 17?

I COULDN'T turn the big Apollo prop either! Only got about 5200 rpm (but 49.9 mph!) with a light load, and only 4600 with my typical cruising load! It would be a great prop if I was running 3.3L 225 HP E-Tec, but that's another 100 lbs on the transom, WAAY too much for the 20' hull!

Well I just ordered the 4B 14.25 x 15. I wont be able to test it for a couple of weeks because I am having the floors redone and the interior repainted. I am also having hoes drilled to raise the motor about an inch.

Mad props!

Hey deadrise, I like your location. We actually bought the building in Princeton where the factory was located. There were still tons of old brochures and rolls of grey puddy. I don't know if that was potter puddy because I don't know exactly what potty puddy looks like.

We bought it to make a private jail but that didn't work out so we had to get creative.

Speaking of a Moesly signature, I'd rather have it on my boat than on toilet paper!

Attached pics show Carl autographing the instrument panel cover from my Seafari. He's also an accomplished painter . . . the last picture of "The Reef" is one he painted! Truly a man of many talents, only a guy who has "been there, done that" could include such beautiful detail! Now we know why he could design boats with such beautiful lines!

Very cool stuff. Moesly looks like a nice guy.

We pulled the console because Im having some the floor replaced and raised. We noticed that the tank is all the way back, I want to move it all the forward about 18" . I plan on moving the battery from the rear of the console to the front of the console and the oil tank from the transom to the front of the console.

Does anyone have any idea how moving all that weight forward will affect the ride of the boat? Will it affect prop selection? Planing speeds? MPG?

it would take me 5 years to paint something like that and it would look like crap when I was finished :)
