Hello,
I own an 04 Avalanche with a 04 115 classic on the back (I know, way under powered).
The motor runs great, but... I'm getting maybe 30 mph out of it, I only get to about 4400rpm on the gauge... Doesn't seem correct.
I don't think the motor height is set up correctly. The motor is currently positioned vertically as far down as it will go on the mounts. Would raising the motor help get the RPM's up to where they should be? Would a jack plate add benefit?
also, What prop does everyone recommend for this boat and motor combination?
On a side note, my buddy wants to pick up an Avalanche. If anyone knows of one for sale on the west coast PM me.
