Hi All,
I bought a 6 hp 4 stroke Tohatsu as a second motor. After 10 hours of break in, I noticed that it does not respond to throttle after ? turns. The motor noise increases a little, but speed (5,5 kt max) does not change. My boat is 15? long fiber v-hull and usually 700 - 900 lbs when loaded. It can reach up to 17-18 kt with my other motor which is an 18 hp 4 stroke Tohatsu. As there is not much space on my transom, I cannot install both motors at the same time; therefore I need the 6 hp also for traveling up to 2-3 miles away.
In order to protect the 6 hp motor from being strained and reach a better max speed, I think I need to change the propeller. The original is 7,8 x 8. What kind of propeller should I use? Is 7 pitch enough, or should I go to a 6 pitch special heavy load propeller with extra large blades?
Thank you in advance for your comments,
Best regards,
Murat
