My Commodore 360 was hauled from the water a couple months ago on a "sled" to remove the original 3-blade props and replace with 4-blade props. While that was accomplished, the cutlass bearing on the starboard side was replaced. After the boat was placed back in the water, I noticed the boat would move and strain against the dock lines when the starboard engine was started as well as the water "churns" out from beneath the swim platform. Looking in the bilge under the starboard engine I can see the drive shaft is turning (slowly) while the shifter is in the neutral position and the engine at idle. Checked the V-drive fluid level and it is at the full level.
I have owned this vessel just over a year and not had this issue before. Has anyone else had this same type problem? What was the cause and what was done to resolve it? - Just wondering if something could have happened to cause the problem during the recent maintenance work performed....
TIA - JJ

Engine shouldn't start if shift lever not in neutral (can be switch at gear shift consul or at trans?) If that isnt the problem seems like something in trans clutch plates or hydraulic pressure to disengage plates bad?

The neutral position hasn't changed and the engine still starts ONLY in that shift lever position however, after starting the engine the water "churns" from under the starboard side of the boat and the vessel moves and "strains" against the dock lines. Additionally, looking beneath the engine I can see the drive shaft turning. It did not do that prior to the boat being hauled and props replaced. This is the reason for my inquiry as to whether anyone else has experienced a similar situation... |

Sounds like a shift linkage issue. I would not have expected that from just servicing the props. Will it shift into reverse?

Sounds like a shift linkage issue. I would not have expected that from just servicing the props. Will it shift into reverse? Yes, that is what a few others suggested on another forum. The engine shifts from neutral to both FWD & REV. I was at the slip a couple days ago and disconnected the shift linkage...it was ever so slightly out of adjustment. However in confirming the neutral position after disconnecting the cable, I started the engine and the prop shaft STILL turns (very slowly). I adjusted the cable and reconnected to the engine...also after running the engine for about 5 minutes, immediately checked the fluid level on the V-drive and it was at the full line. The service manager called me shortly after they had begun work to tell me the "mechanics were having difficulty getting the starboard prop off the shaft" but while we were talking on the phone, he said "oh, never mind...they got it off"....that makes me wonder...what did they have to do to get that prop off the shaft and am I now seeing the results of their efforts in a prop shaft that turns in neutral? They returned the boat to the water after the starboard cutlass bearing was replaced and the new props mounted....then they replaced the raw water impellers for both engines and the genset over the following week in one of their slips. First time I started the engines at the service marina, I noticed the boat strained against the dock lines. It did not do that when I docked at the marina bringing the boat in for service. - JJ |

Hopefully, they didn't beat on something and screw-up the internal clearances on the shifting mechanism trying to get it off.
