I have a yarcraft storm 1895 with a 15 horse 4 stroke kicker(not big foot).

Was wondering if i will get better handling with a different prop. I have a tr-1(it sure seems like it has to move a lot). Most of my trolling is with rpm about 1400-2000. Like to have a speed range .5-5 mph. Cant quite get to .5, but close.

i have a 3 blade 9 pitch currently

any advice

lower pitch?

4 blade?

what are the pros and cons and what would i gain with each

also
whats a reverse exhaust diffuser cup?

will that change my forward trolling
