The TK luck has held true to form this afternoon.
After looking at a marine suppliers website, finding out which starter motor they recommend as a replacement of my original unit, noting that they say "a direct replacement for Mercruiser part numbers tiddly pom and whoopy do.
I went onto the doug russel website and entered my engine number to cross ref the part number given with the official mercruiser part number. Yup part number tiddly pom.
Back to the suppliers, yep defo replacement for part number tiddly pom.
So I ordered it and also a bolt kit that is recommended.
After a great deal of cursing, swearing, standing on me head, crying in pain at me agony filled knees and generally wishing ill of design engineers that leave no room to move a spanner more than 1/8th of a turn at a time, I got the old motor out and new one in.
Power on, ignition on, whirrr brum graunch, CRACK! key off, all in the space of a second or so.
Removed starter and the casing has caught on the ring gear.
New starter was not a like for like replacement, new one was the latest lightweight PMGR motor, so comparing the two to see if they were identical was not possible as they are completely different, even in overall size.
Bolts suplied have knurls on the shanks that cut into the slightly smaller holes in the ally casing on the starter motor, so I put down the stiffness of the threads towards the end, as the knurls cutting into the casing.
Damned silly bolts
Not too concerned with the wrong part supplied, or the wasted afternoon spent upside down in the bilge.
I am concerned with the loud sharp crack just before I shut the motor down.
At best, the ring gear has moved from its seat on the flywheel, at worst, cracked ring gear, flywheel bolt or God knows.
One thing is clear, the motor has to come out for the flywheel assy to be inspected.
Who is liable for the boatyard fees?
Sent a friendly message to the supplier, not angry, been in the motor trade long enough to know s hit happens, but can't afford the marina workshop costs and don't have the tackle to pull the motor myself.
Advice?
Thanks.
