dajome Someone has kindly photographed the pages from the Crescent Owners Manual and put them on the web but I can't find the link. However, I have 12 jpegs of the relevant pages for the 3.9HP - if you send me your email address to david "at" dajome "dot" com (I'm not allowed to post email addresses yet), I'll email the pages over to you.

Me Too!

Hi everyone,

I have been given (yes!) a Crescent 4 outboard, which is the 1970's version of the Volvo Penta 3.9 / Archimedes 4HP. This example is an external long range fuel tank version, but with no tank. I am hoping to get it running with a very small internal tank I can just about fit under the hood - my dinghy is very small.

I too would be very, very grateful to anyone who could supply either a scan of the relevant manual, or just details of the fuel mix, spark plug type and gap, points gap, timing etc. I have recently found a link on the web, which it seems I'm not allowed to post here, but it appears in Yachting and Boating World Forums - which may be relevant - and I hoped including it here might help someone. I was going to try it out with a 25:1 mix, so I've been saved from that mistake, I hope. That forum says the Volvo Penta 51 (5 HP similar motor?) runs on 50:1, so I will try that out when I find a new spark plug to fit.

My boat is a home-built 8 foot pram with standing lug, so I would not welcome a tank under foot at any time. I also have an old British Seagull 40+ from 1954 - nearly as old as I am, but have yet to try it out on the boat. The Crescent is lighter and cleaner, and may be better as it seems in good condition. I hope I can get it running.

Crescent 39 query

Hi, Cfleeming seems to be very popular - the only person on the planet with a manual for the Crescent (Volvo Penta) 39.
I also am on the lookout for this very rare information as I have one with no spark and the electrics are "interesting" to say the least - I think mine have been bodged as the connections don't appear original and don't seem to be complete. If you're willing to do me a copy (paper or electronic) I'd be happy to pay for your inconvenience.
I live in the UK
Many thanks
