Avon SR 5.4 project

GrahamSR5.4 · 29 September 2020, 10:43

Bought my first Searider 5.4 and decided to restore it completely. It was built in the 80s and is still running the original Yamaha 70hp 2 stroke perfectly.

Day 1 down and the engine is off, deck is stripped and ready for sanding

Plan is to coat the deck and hull black and fabricate a custom console + seats

Welcome to Ribnet

Nice project

I don't think that's the original motor, that looks like an ex mil-spec boat (Grey dust and straps on tubes gives it away) that would have had a Merc 75 on it at a guess. Looks to have been refurbed before.

Cheers ! Ah right interesting, just presumed it was as it's a 1988 motor and no sign of the serial plate on the transom. Yeah it's an ex police boat you can still make out the lettering on the tubes which have seen better days !

I think the rubbing strake has been changed too I'm sure it should be flat on a searider

Yeah the strake is new, tubes are painted grey and look terrible so probably end up getting new tubes for it at the end

Day 2 : I got the majority of the deck sanded and fuel tank surrounds removed as one was starting to rot. Will be fitting a bench in it's place to store tanks inside. Another half day of sanding left and it will be ready to flip over and get cracking on the hull !
