"Hi,
I have a 1989 2688 WA Renken with a OMC King Cobra 5.7
When i purchased it last year, The boat was a mess. The current owner had the engine rebuilt.
The engines runs great.The first time i took her out after two test runs the engine coupler had striped, pulled her out and pulled the engine, installed a new coupler.installed new gimbal bearing,bellows and so forth, By the OMC sterndive manual. I also found that the esa was disconected and had to re wire the complete wire harness. Installed a new cdi module, pertronics unite, CDI resister before the coil, Ajusted all the shift linkage per the OMC manual and got the engine to run at stated rpm in manual and shift very well.All was working great untill last week.
I was fishing a tournament and lachted on to a Lobster pot line, pulled it up, pulled it a little with the boat in reverse, pulled it up again and broke it loose. Since then when i go from reverse to forward, get on the throttle, as she is coming up in RPM she will make a thump noise for only a second and then be fine, Almost sounding like im hitting a little log with the outdrive and then its fine. The only thing i noticed is since i put her in the water before the pot pulling is,I'm not getting the rpm at max throttle i should be. she will only run 4200 max. The boat should wieght about 4600 pounds dry and she currently has a 15x13 prop.GPS top speed is reading 22knts
Could the noise be the prop is spun and there is a slap in the hub of the prop?
Is something starting to happen with my upper or lower case,gears ect?
Does any have a sugestion on a posible size prop
I should be running?
Any sugestions would be helpfull, My last vessel wasa twin inboard, Not used to this fish.
Thank You, RC"
