40 hp Lark

[geoffwga1]

Mornin all.
Looks like I have an opportunity to buy a 70s boat, trailer, and motor for what I think is a good price.The boat is a stalled project but it's the motor that interests me.Don't know yet what the year or mod # is but it looks from the picture like late 50 s or early 60 s.Guy says it ran OK last time used but to be taken with usual pinch of salt.
I hear many good things about Larks so was wondering if anyone had any thoughts on it.He's only asking $175.00 for the whole shebang.

If the trailer's good, that's $175 right there. If the motor is complete, has compression and controls, lower unit not filled w/water etc.. should be runnable w/undefined effort and $$. If you're looking for a project, I don't see how you lose money if the trailer is useable.
Good luck!

If it wasn't used in salt water it's a good deal.

Well, the Lark, prior to 1970 was an excellent engine. The 56 - 57 was my favorite models, but I happen to own three of the later one's myself. A good compression number on these is 100 - 130 PSI on each cylinder. The 57 - 61 models will have the high compression heads, with the compression releases, so they'll typically give you higher readings. For the price, you will do good. Even if you pulled the motor off and kept it, the boat and trailer is worth about that. Like boobie says, fresh water use is a better deal. Salt water would be a bit tough to deal with, should you start taking things apart. Bottom line is, the Larks were in my oppinion, the best motors built and very reliable. Spend about $150 and do a thorough tune up, and you'll have a motor that will last you for years. New ignition system, waterpump and lower unit seals and you're set for life.

Thanks guys.You have reinforced my gut instincts.As this motor is in idaho I doubt if salt would come into it unless it has travelled.I'll be able to tell you more when I see it and get the model# and do a compression check.

Cool deal. Anything east of the Cascades should be safe from salt water use.
