Hey all, long time lurker, normally would search but can't seem to find a solution for my info. Would appreciate feedback or ideas.
2008 Chaparral 256SSI
VP 8.1 GXI-J SN#3869415
Prior to everything boat ran great, starter gave out, bolts were corroded and decided to remove motor for a bunch of other preventative mx. Replaced everything manifolds, risers, elbows, plugs, coils, motor mounts, starter, bellows, oil, etc. All parts were replaced with genuine VP oem parts. Batteries less than 8 months old and seemed fine prior so did not replace.
Reinstall motor and she fires up and runs great. Take it out a few times with no issues. Did notice the current starter issue once the day prior to it not working at all but tried again and it fired right up.
Now when trying to start the starter engages the flywheel (audible clunk sound, not a click) but does not turn over the motor.
I pulled off the water pump off and rotated the engine by hand and everything moves free so that was a relief.
I noticed that there was EVER so slight movement in the starter even though bolts were tight. Loosened and retightend and was able to start the motor once. When I tried again no start, same issue. Pulled the bolts one by one and one of the bolts was too long. Replaced with a proper length bolt and it everything snugged up nicely. Still same issue. I noticed when I went to turn motor over by hand I heard the starter ring gear click back and "fall" off of the flywheel. Possible binding? Or alignment issue?
I also checked voltage drop while my gf turned the key. Red lead of MM to starter solenoid post and black lead to negative of battery terminal. After trying a bunch of things the battery was somewhat low so I know I will need to recharge (what I am doing now) but here are my numbers. 11.9 without engaging starter 11.1 while trying to start. I am going to check voltage drop from starter post to positive battery post next. I am trying this with and without a jump box to get it some extra juice in case battery voltage is still a little low.
Big picture question overall, has anyone experienced this, and should I focus my effort on the starter mounting itself? Or is this for sure an electrical gremlin/grounding issue that I am going to have to flush out. Problem was progressive in nature and not all of a sudden.
Thanks.
