I have a 4 stroke 9.9 merc and use it for trolling only. My question is: can I slow down my trolling speed by going with a 4 blade prop???? I don't know the pitch on my 3 blade, but would I be further ahead to swap out pitches on the 3 blade????
I don't have faith in my boats speedometer, but estimate my slowest trolling speed to be approx 1.5mph and want to get down to 1 mph or less.
