Fitting up and over wheels.

[Bighag7]

Hi Guys,
I've just bought some up and over wheels for my Zodiac Futura Fastroller 4.7m with airdeck.
I have the original wheels with the stud fixture and "crank" style screws but they drive me up the wall to keep bringing them on and off, hence the up and overs.
I have to drill the plates for the new wheels onto the transom, can anyone recommend a glue or sealant I can use to maintain waterproofing of the transom?

I just use a Marine grade Silicone for waterproofing and seems to work well.

Great,
Thanks for that I just bought some 291 Silkaflex Marine sealant off of Ebay.

Are you talking about through-bolts, or screws?

For through-bolts, best would be to drill, paint the bore with epoxy, then install the bolts.

For screws, drill, insert the screws, remove the screws, inject with epoxy, then reinsert the screws.

Silicone doesn't seem to stand up to the marine environment too well in the long run. Considering what the cost of repairing a rotten transom is, why take a chance?

Yes they're screws. What Epoxy would you recommend? Also, do you think the Marine Grade 291 to be not up to the job?

I think jyaski might be talking about bathroom grade silicon, which is i nthe chocolate fireguard category....

I've had no problems with Sikaflex, I jkust can't remember which grade, as they produce different versions fordifferent applications like elevated temps, constant submersion, movement etc etc. Google them & you'll get the data sheets on the Sika Industries website.

Just checked the website and the 291 is ideal for above and below the water line applications. They've just brought out a new one called the 291i which cures faster.
Thanks for the help guys!!

As I recall, there are some 20-odd different "Sikaflexes" for various purposes. Of which about 2 are available to any degree in the US (and they are usually construction adhesives.) To say my knowledge of their products is lacking would be an understatement.

And yes, I was talking about standard Silicone caulk. I always thought the Sikaflex used in marine applications was a polyurethane adhesive/sealant similar to 3M 's 5200 (or the less tenacious 4200.)

Sorry for the mislead;

291 is an adhesive as opposed to a sealant, all the better though and perfect for the job. Just don't get it anywhere you don't want it!
