Fitting a new log is this safe?

[RIN]

My old Incastec Supermaxi has stopped working and is no longer made. I have been looking at the NASA Clipper range, but the hole in the hull I have for the Incastec transponder is 44.5mm (1 3/4") whereas the hole for the Clipper is only 42mm.
Anyone have a view on whether this would be safe?

Also anyone got a good/bad word for the Clipper Log?

Many thanks

leave the old one where it is, and drill a new hole for the new one!!

Crikey - I would rather reduce the number of holes in the hull than increase them!

Depends on the flange diameter of the new transducer. I would like to have at least 10mm contact all round so a flange diameter of at least 64.5mm would be needed. Fit the transducer in the middle of the hole with plenty of sikaflex and fit a pad on the inside if the nuts outside diameter is less than the above size. Don't over tighten the nut.

There should be no problem.

HOPEFULLY

I would have thought a 1.25 mm gap all round would be just enough to get some sealant in, it should have plenty of flange on the outside.

Your alternative is to wait for warmer weather or find a good heat supply and fill the tiny gap with epoxy mixed with micro fibres, a lot of trouble for a vey small gap.

It'll be fine, the tiny gap is of no consequence. Many people would drill oversize to that sort of clearance anyway to ensure the plastic was not stressed in a tight hole.
