It appears MC is now recommending using 3M Brand Adhesive on Bravo 1 Bellows instead of their standard bellows adhesive. Both my Bravo 1 bellhousing and gimbal housing water hose openings are slightly worn. The groves and ridges are still there but worn due to years of corrosion. It seems to me that a good coat of 3M adhesive between hose and metal would protect existing threads AND assist the tapered insert in securing the rubber water hose to the bellhousing and transom gimbal housing. However, the manual doesn't state to use 3M on the water hose like it states for the bellows. Any suggestions would be appreciated.

Where did you see MerCruiser recommendations for 3M over their bellows adhesive?

Perfect Seal is better for the water inlet hose.

The 3M reference seems to be an original name and different part number from Merc as they listed part number 92-25234-1 as 3M Brand Adhesive in the sent manual and/plus Quicksilver Bellows Adhesive as part number 92-86166 in other manuals around the same timeframes....The numbers and names have changed slightly over the years which is now ending with 92-86166Q 1 - Bellows Adhesive for now....They tend to change names and numbers often....I'm sure Merc had some sort of $ deal made with 3M in the beginning and may still do.


For example the following older manual lists both numbers right next to each other,

Quicksilver 2-4-C Marine 92-825407A2 Lubricant
3M Brand Adhesive 92-25234-1

Quicksilver Perfect Seal 92-34227-1

Quicksilver Special 92-13872A1 Lubricant 101
Loctite 8831 92-823089-1
Quicksilver High 92-816026A1 Performance Gear Lube

The 3M is shown to help hold on the O-rings (plus a few areas all around the drive components) when installing the drive unit to the bell housing.

I have a tube of black 3m adhesive and it doesn't look anything like translucent bellows cement. I suspect the 3m stuff coats and develops a bond between materials more so than the traditional bellows cement. Once it cures, the 3m stuff seems to be more hardier. THx
