Need to Raise Outboard - Help!

[NickF]

Hi All,

I need to raise my 175hp outboard 2 holes on the transom. It is currently on the upper most holes meaning it is at it's lowest setting. If I unbolt the 4 bolts and lift it 2 holes what sort of silicone/sealant do I need to use to ensure no water gets into the timber in the transom over time and have peace of mind knowing it is sealed properly?

The reason for the lift? : The cav plate never sees daylight unless I am running at WOT which is VERY rare as we cruise alot. The boat is backend heavy and there is excessive drag and better performance is achievable. I tried a SE Sport 300 foil but even that rides under the water all the time so the motor is definately too low.

Anybody able to give me some advice or feel like helping with the exercise?

Kind regards

Nick

Hi Nick, rather than drill more holes in the transom what about a jacking plate? Like this:

I reckon the freight is excessive but you could get it a bit cheaper. Also you can make adjustments yourself to get it spoton!

Hope this helps

Sikkaflex is the go for that application.

I don't need to drill new holes, the ones in the transom are fine, the outboard just needs to be moved up 2 holes on the outboard mounting bracket. The only issue is that the steering cable has no stretch so I would have to unscrew the cables to allow the outboard enough room to come off the bolts and be lifted. Make sense?
