prop selection

[cat311]

I am going to be re-powering a 22' renken seamaster I/O. I was thinking of using a 350 block with alpha 1 outdrive. I was wondering if that setup would be able to troll @1.5-2 mph. If I were to uses the 350, what prop would be the best for this setup? thanks matt

Ayuh,... Welcome Aboard Matt,...

There's many ways to control trollin' speeds,...
5gal. pails drug along side, drift socks, trim tabs....

Just guessin',... probably a 19" or 21" prop.....

edit; carried from yer other thread...

Few to no boats are able to be propped to run properly at wot, yet run slow enough to troll...
There are Many options, without runnin' a kicker...

On my barge, I use trim tabs, 'n drift socks...
I also have a torque-shift prop by Land & Sea...
It trolls at 11" of pitch, 'n shifts up to 'bout 20" at wot...
With the trim tabs full down, I can idle/ troll at 1.5/ 2 mph...
Throw out the drift socks, I get down to Sub-1mph...
