I am a new poster and hope I have this post in the correct forum.
I have a 1973 Uniflite 31 Sport Sedan with twin Chrysler 318's with Paragon 1.5:1 V-Drives.
If the information that I have been able to locate on the internet is correct, it is as follows:
Weight Dry: 13,500lbs
Fuel Capacity: 2 x 83 gallon tanks, total 166 gallons
So figuring that the loaded weight would be around 16,000 lbs with 4 adults, fuel, fishing equipment, etc.
When using her last year, we were never able to get her on plan. WOT was about 3400 - 3600 RPM and she just wouldn't popup on top.
We new that we would be pulling her out to have fresh bottom paint this year so we just used her at hull speed.
We pulled her out yesterday and the props just look like they have to much pitch. It is hard to read as the one prop is in pretty bad shape and will need to be replaced.
The other prop I can make out is 16 x 15, if it was a cupped prop, then it has worn off.
Does this seem like the right prop for my setup? She acts like she is over propped.
The 318's seem to be running fine and no problem getting well past the 4400 RPM when not under load. We will going through compression checks later next week.
Any help would be greatly appreciated.
Thanks
Danny
