Ok, so had the propeller hub blow out/wear out. Had a professional install a 4 blade aluminum on it. He said would be better take off and lose some speed. We lost 13 mph at 5000 rpms, 25 mph tops with only 3 people on board. The old propeller (3 blade SS came with boat used) was then repaired/rebuilt. Put it back on and still running 25-28 mph, 5000 rpms with 4 people on it. Before the issue was running 38-40 mph. Does anyone have any suggestions or explanations?? 2012 Sundeck Sport with a Yamaha 115TX. The take off out of hole is about even between the two.
Also, does anyone know where to get a video or instructions on how to tighten the shifter mount. Some bolts are working loose. Im 99% sure the two issues are not related. Thanks very much. First post.
