hi all, i bought a boat today with a 4hp chrysler 2 stroke engine but the bloke i bought it off was useless except to tell me i need 2 stroke oil and unleaded but that was it.can anyone tell me what the correct fuel to oil mixture for this outboard? 24:1, 50:1, 100:1, or something completely different, cheers

Assuming it's a 1962 to 1984 model, these guys will sell you a manual: www.autorepairmanuals.biz/site/573683/product/0893300187

Unfortunately I guess it might turn out to be worth more than the engine.

Also came across a reference that model number 43HOA, from 1980/81, runs 50:1 mix
