My question is should I stay with a 19p if I went with a 4 blade Spitfire or change pitch? Anyone with this boat tried this?
I have a 2025 Impact with 19p Tempest as well. Torque it to 140ft lbs. I think there is old info for like 90?
I have a very small amount of rattle almost not noticeable,
Worth a try if you aren't already at 140 or so.
I have a new 200 Merc.
I'm wanting to try the 4 blade aluminum spitfire just to see how it performs......
