Shetland 535 rebuild.
Posted: Mon May 03, 2021 11:11 am
Five years in !!! spare time project.
Retired, moved and now live in a cabin on Brightlingsea Creek, Essex. Built a dock in the first year, so had to get a boat !!!
My first (and only) boat restoration. I have never owned a boat before but have been around them.
Only got the cabin and door left to do !!!.
1972 Shetland 535 bare hull rebuild, all holes filled and damaged repaired. There were 127 holes through the fibre glass when everything was removed. 1983 Mariner 60 (Yamaha 60C rebadged) rebuilt. Cost over £1,000 in bits (£400 for the CDI alone). Did the work myself. Power head off to access gear selector. One in 3 bolts sheared so have become a dab hand at threading and helicoils. Cross hatching still visible on bore, all seemed original so no need to strip the block or head. Compression 145 psi and 143 psi. Old motor with very low hours, transmission was also oil tight with no signs of wear. Carbs rebuilt, vacuum balanced, idle mixture and timing adjusted. All service items replaced and new coils, fuel pump, thermostat, water pump and gear selector fitted. Achieved 29mph (SatNav) before running out of revs (prop too small and wrong pitch, now fitted something a bit more leisurely). Did get out of the hole very quickly !!!
Everything replaced except the rev counter and log. Modified motor well drains to empty all debris and water. Cabling tidied in an umbilical. Hatch fitted. Floor sub-frame created. Hull gel coat retained, top deck re-painted. Twin bilge pumps, twin 120 amp/hr leisure batteries. Added a volt meter, temperature gauge and remote choke switch. Fitted tinted screens and got a cover made.
Any ideas on the cabin door, I fancy a barn type door, possibly modify the existing item ?
Mariner say 50:1 petrol/oil, Yamaha say 100:1, so running 75:1 with good quality oil as I will very rarely be running above half throttle, have to spend first 30 minutes of any trip at just above tick over due to speed limit.
