I have never bought a boat before, but am considering a boat with an old 1987 Johnson Outboard engine on it. I don't know the technical words or detail but the owner said that a previous owner had gotten ride of some kind of automatical oiling feature (?) of the engine and that he just mixes oil with the gasoline now and it worked very well. So this goes to show you how un-conversant I am with outboard engines. I'd like to buy this boat as it is in excellent shape.<br />The engine is 40 horsepowers. <br />Anyone with suggestions on what to look out for, what to check, etc. Hate to buy it and find myself stuck with a huge repair bill. The current owner says it runs real smooth and hardly burns any gas or oil.

Re: Important Things to Check Out

geoduck, take the engine to a boat mechanic. If they are not busy they could check the compression of the cylinders without much trouble. That would tell you the general condition of the engine. Also they could see if the prop shaft is straight. Like middleground said , have an experienced outboard person look it over. I, personally would want to test drive it. and is there any rot in the boat?

Re: Important Things to Check Out

Hiya & welcome,<br /><br />When I go to look at an outboard;<br /><br />1) I ask them before hand if they're set up to show me it running. <br />2) I take a compression tester, plug wrench, flashlight, multi-bit screwdriver and rag.<br />3) I check compression (ask if that's OK first)<br />4) then I'd want to see how it runs.<br />5) after running I drain a wee bit of oil from the lower unit (looking for water and metal filings on the magnet) again, I ask first and don't make a mess<br />6) During this I'd be asking about the repair/maintenance history (bills? spare parts?), and giving it the general once over.<br /><br />The largest pitfalls are 1) an engine that is either worn out, has a broken ring or other "top end" damage. That's what compression testing can tell you. They can run surprisingly well with one bad cylinder, <br />and 2) a lower unit that is bad or on the way out. (that's why I look for water/filings). Of course if they're trying to hide a problem and the oil is brand new won't see anything. Other prob's could be there (electrical dirty carbs etc) but they don't usually cost ridiculous amounts to fix. Rebuilding a powerhead or lower unit could well cost more than the motor cost you, especially if you pay someone to do it.<br /><br />I'm assuming this is a private sale, not a dealer. (?) Given that you're a newbie to outboards, if you don't have a friend who is very well versed in OB's, you might wanna consider paying a dealer/mechanic to check it over for you before you buy. <br /><br />If from a dealer, they'll often give you some kind of warranty if they're confident it's decent (30, 60, 90 days?)<br /><br />If you buy it, either expect to buy a service manual and get your hands dirty, or budget $ to pay to have the water pump serviced, lower unit lube changed and a general tune up done. I don't mean to scare you off, boats are great but having either mechanical ability or disposible income (or sometimes both) will eventually be required!<br /><br />Also, if you buy don't forget the trailer... pay attention to the condition of the tires and ask when the bearings were last re-packed. Then do it yourself before long (because they always say "just this spring" even if they weren't ;) )<br /><br />Good luck!
