Timing 90 degrees out?!?!?!?

RiPsTa · 07 June 2010, 18:25

Bought a 16' seaskate dory last year as a stop gap because i could'nt quite afford the rib i wanted. It has a 1997 Mercury 40hp elpto outboard 2 cylinder 2 stroke S/N: 09943108. After using the boat once there was a loud clonk and the engine stopped dead, to cut a long story short the magnets had dropped out of the flywheel and smashed so i ordered a second hand as new flywheel off the internet. I fitted the new one and have been trying to get the engine running ever since (even resorting to a full rebuild).

Today i have had an electrician out to the engine and he has told me the timing is 90 degrees out?, i have been trying to find part numbers for flywheels to make sure this is the correct one and as far as i can tell it is.

Has anyone seen this before?

P.S. Thanks for any help in advance and if i can help with anyone elses problems i will do my est.

From the info given. The flywheel P/No should be 276-823760A4. It is possible you have been sold a flywheel from a 3 cylinder which look similar but have the timing magnet on the centre boss mounted in a different position.

Thanks for the reply, thats pretty much the conclusion i was coming to. The number on this flywheel 276-823760C2 but i cant find any info on it whatsoever so i can only assume the difference in a 2 and 3 cylinder is the A4 and C2 at the end of the part numbers.

I have just had an email from RIBS Marine to say that the part number for my flywheel should be 261-859233T26. This is starting to get really confusing.

Edit: After a quick google search 261-859233T26 supercedes

859233T18
859233T8
9008A40
823760A4

so would i be right in assuming any of these flywheels would work?
