We were having issues with the prop earlier and couldn't get on plane. We dropped the pitch and some blades and increased the RPMs. It now takes about 100 yds full throttle to get on plane with two guys and batteries, fuel. Top speed is 38 mph. Is this normal with this setup?

Re: Ranger 692 w/ Mariner 150

One mechanic had said that it is alot of boat for that motor. However I have seen 90's & 115's on much larger boats. It had a five blade SS 21 and now has a 17 3 blade aluminum. All cylinders are around 108 on compression test. Mechanic says all carbs are ok. Not sure what the heck is going on. Does anyone have a similar set up? How does it perform?
