resealling engine mount bolts

[edson1988]

the engine is a 1989 evinrude 110 hp. is it possible to reseal these bolts without removing the engine from the transom ? and do these engine have the lift rings built in or do the have to have the lift ring tool?

As long as the transom is solid you can remove one bolt at a time then clean out the old sealer, re-seal and replace.

I think what you are planning is very good, but it may be better to pull the motor and clean off all the old sealant and go back with new. Part of sealing the motor is having a bead of sealant around the bolt holes in between the "mounting plate" and the transom. If you don't have an easy and safe way to lift the motor off, your local shop should do it for 2 hours labor or less. That's what I ended up doing. I'd guess a reseal on your motor should last quite a few years, so it's not like you have to do it every year. If you have an engine lift and an extra pair of hands to help you, then probably not too bad on your own. I just wasn't comfortable trying to do the job solo on a 500lb motor hanging from a rafter in my workshop (no engine lift).

Yes. Another poster brought up a good point about cleaning the old sealant..... it should depend on what was used as sealant. If it was silicone then I would go through the work to lift the motor (it's about 325 lbs) and clean it all off.

If the transom is in good shape then reseal the bolts with 4000 series or 5200. If it is in existing good shape then pull the bolts individually, make sure the hole is dry and clear and reseal with 4000 or 5200.

DO NOT run a bead of sealant around anything but the bolt. I have seen too many people run sealant all the way around which only wastes sealant and has no effect.

Be advised the lower bolts are the ones that normally leak since they are normally under water whit a boat is at a standstill.
