Hi Stuw and Will
At present I have a 35mm 3 blade prop in the boat which I was planning to use with a 540 80 turn brush motor on 2 S which is about 9000 rpm.
Also have a C3542-1250kv which will bolt straight in with a different uni joint and with the same battery, the same rpm.
Power would about 4 times more.
The changes are from other boats I have restored or made .
I added chine rails to my 1920 Gentleman's Runabout and turned that from a wet running boat into a dryer running boat.
Chine rails had not been invented in 1920 !!!
It still not great on the turns which I think spray rails would help ??
So a two years ago, I pick up a Queen which is nice boat, but it was vanished with a wire brush !!
Vanish runs, leaks from wet running, windows that leaked and roof with broken pieces.
So far re-vanishing, replacing the cabin windows and repairs.
I ran the boat, the CG was too far forward( drop a lot of lead into the stern) which stop it from running like a tug.
So back in the shed, spray rails and chine rails plus moved the battery to forward of the rudder.
Still had to add lead around the rudder.
The CG back to about the same.
Next trip to the water, the boat sits up on the plane, dry, turns super great and that is flat-out!!!
TOTALLY HAPPY !!!
NO, Will, just a Mad Tasmania stir !!!
