Launch Wheels

Hello!
I am about to install a set of launch wheels on my sib / rib.

Why sealant would you recommend using for the holes I drill to affix the wheels?

Thank you

Most would recommend one of the Sikaflex sealants - I dunno which one would be best - 291 maybe?

I fitted a pair of the small roller type wheels on mine. These suit me as I launch on concrete or hard sand. I didn't have any Sika handy at the time and used "Tec 7" instead as I had some and it was grey, matching the fittings. It has held up very well over a couple of seasons.

I used silicone bath sealant when I fitted my launch wheels, I don't know if this was a suitable product to use (I'm sure there are marine specific products as mentioned above) but four seasons of use and it still looks perfect.
The transom mountings for the (roller type) wheels did have a rubber ring seal around the edge so the silicone sealant was just for peace of mind really...the fitting instructions did not specify using anything at all.

I used 3M 5200 on my brackets, which are permanently mounted. Anything below water line should have an adhesive/sealer. Sikaflex counts too.

I have just tried installing the wheels purchased with the sib but no matter where I put them they are in the way of the outboard when on full lock.
Anyone else had this?

My launch wheels cleared the outboard motor with no problems, on my Zodiac SIB.

I guess it depends on the size of the transom.

the wheels are only a problem when then outboard is turned full to the right and then arm touches the wheels.

Take them off (2 bolts)and store next to transom each time

I personaly would not use silicone bath sealant ,as salt water does not go well with it, a sikaflex waterproof sealant would be better,can t remember which one i used but it was £18 a tube dam expensive for a few thimbles full lol.
