Re: 1987 Evinrude 4hp - Flywheel threads?
It is sometimes a problem to find the Belgium built models on the American parts websites.
I suspect the problem lies with models built for the European and UK markets.
Take at look at the official BRP parts website at
http://shop.evinrude.com/ go to the electronic parts catalog and find E4BRHCUD
I think, apart from that number being for models without an integral tank (BRH models), it will match yours.
The parts list itself does cover the models with an integral tank, namely the BR models.
I have not compared what you have found for an 86 model with the parts list for the above models but at a quick glance they appear to be the same.
For parts suppliers in the UK try
Oakley marine in Brighton,
www.outboards-direct.co.uk.
or Willsmarine in Kingsbridge, Devon
www.Willsmarine.co.uk
I have had good service from Oakley and users of
www.YBW.com/forums have reported good service from Willsmarine.
If you quote your model number to a UK dealer they should be able to match it to the parts you require. Crowley and other American dealers may not. You won't be wanting to import parts from the USA presumably.
