Re: help w/my 140 parts

any GM neutral ballance flywheel will work as long as the diameter is correct, all have the same bolt pattern on the crank,just go to your local auto wreckers

Ayuh,... Timing gears are replaced as Sets,.... Don't replace either 1, without the other...

Re: help w/my 140 parts

You can't buy a timing set. Only the cam gear or the crankshaft gear.

Ziggy posted 2 links you can find the gear at, the cam gear part number is 43-46745 (old number from Mercruiser) the new Merc number drops the 43-.
