Worn out/damaged prop symptoms?

[Kevoz]

Is it possible that a worn out/damaged prop can cause under rpm conditions? In my other threads I have restored a 88 glasstream cuddy with a reman from rapidomarine and have never gotten the new engine to get the boat out of the water on plane... (2800rpm max)The boat has gone home to Indy but I still have the 'it beat me' nightmares...
Cheers,
Kevo

What engine, what outdrive, what prop, what diameter and pitch? Just because you have a remanufactured engine does not mean is developing full power. After installation, timing and carb adjustments are required. If this was a short block, whoever installed the heads may not have adjusted the valves properly. So before blaming the prop, make sure the engine is up too snuff.

Checking all of mym previous posts would have prevented you from making this post..

I know this is an ooooold post. I'm looking for a re-man 4.3 for my '93 Fisher 19 I/O so I read that novel about your purchase from Rapido and all your trials and tribulations. I commend your for your dogged stick-to-itiveness. Now I see this post. Reminds of the time I got the bow line stuck in the prop of my old boat ( 800hp Blown Big Block Warlock Cat....lot's of power..tons more than a 4.3 obviously..) I realized I had something wrong 'coz my rpm's were down ( not sure how much exactly, just felt it and shut it down). Long story short, check your outdrive. Could be something causing a huge amount of drag. That could 'splain the pinging, too. Ever heard a car ping going up a hill?
