Raising engine. Any 1st hand experience?

[family affair]

I'm going to be raising my engine soon. I have concerns that the 5200 used between the engine and transom could make it a tough separation. Any tips?

Also, I used a small amount of 5200 from the tube and made sure all the air was purged prior to capping it. The tube states all adhesive must be used within 24 hours of puncturing the seal. Is this a hard and fast rule or is 3m covering their tail?

Thx

I raised our 2002 200 HPDI about a month ago from it's original location. Not sure it was 5200 or something similar (maybe 4200?) but it was not difficult to do. Used the trailer jack and a few blocks of wood, cut the caulk with some upward tension on it and it came right off. I intentionally left the two bolts in and loose that are located where the slot is when we were raising it. Once raised, we installed the other bolts , sealed and tightened them, pulled out the bolts in the slots and sealed them as well.

I am no expert at mounting and/or raising outboard engines, but I did not see a reason to squirt 5200 between the transom and the outboard motor bracket. Yes, I don't want water entering the four bolt holes in the transom, but that is why I sealed these holes.

Any tips?

Don't use 5200 when a sealer is called for. You could lose chunks of gel coat should you have reason to remove or adjust the engine again.

I've learned over time that 'tweaking' has its limits. If your performance is OK, it's unlikely moving the motor will yield much. Try out the new position before applying sealer, the move may be detrimental.

You might be able to use the tube again, most likely the nozzle will plug and you'll have to slit the tube. I've found it can last a good while in the fridge ... :wink:

I agree. This is the wrong application for 5200. 5200 is WAY overused in the industry and many think it's a "wonder caulk" to be used everywhere. Truth is, although it's excellent at what it does, it has only limited uses. The bolts are the structural part - you only need a quality sealant to keep water intrusion out. But, since you already have 5200 there, you might be able to pull a piece of thin fishing line through it (and around the bolts) to cut through most of it.

As far as the 24 hour thing... If the stuff hasn't hardened up you can reuse it (somewhere else).

The engine came off without too much difficulty. I am grateful to have the guys at the rack allow me to use their tow motor to help out!

The sealant in place was the consistency of 5200 and did a heck of a job of bonding the bracket to the transom. I little lifting and some muscle popped it off.

I'll start a separate post for results.

Thanks for the info all!
