I just bought a 1985 bayliner capri 1900 with a force 125 on it and have some questions about it. first off I didn't look to see if it's a 2 or 4 stroke and what all do I need to do before I take it out on the water? The prop. seems to be in good condition but it does have some deep scratches on it.

Re: New(used) engine check-up, newbie boater

I'm pretty sure it'll be a 2 stroke... I think all force's were. My standard practice on a "new to me" outboard is:<br /><br />1) get a service manual (unless it is one that I'm familiar with)<br /><br />2) replace impeller even if it pumps water OK (unless I'm SURE it's been done in the last year or two... like previous owner gives receipt that shows date). Usually when someone says it was done a "couple" years ago, its either never been done, or was done 10 years ago.<br /><br />3) do a compression test (normally I'd do this before I buy a motor)<br /><br />4) new spark plugs<br /><br />5) inspect wiring & fuel lines<br /><br />6) replace lower unit gear oil and seals/gaskets on drain & vent plugs (if gear oil is milky, you've got a water leak into it). Re-inspect it after your first few hours use. (pull drain plug for a second, you can leave the vent closed), it should look like new, not milky.<br /><br />7) inspect/replace drive pin ("shear pin") if so equipped (and buy a couple of spares to keep in the boat)<br /><br />8) inspect fuel line / primer bulb (handy to take a spare along if you have one)<br /><br />9) grease all the things that should be greased (including steering cable)<br /><br />When I go out with my "new" motor, I feel mucho better having a kicker motor on the boat in case of problems/catastrophe. I guess it depends how far from the launch/shore you're gonna be going. Definately stay close until you know it's running alright.<br /><br />you might wanna pre-mix the gas & oil (50:1) until you're sure the oil injection (if so equiped) is working. Mark the reservoir and see that it's using appropriate amounts of oil for the gas your burning... if it's correct, then stop pre-mixing. You might also wanna put the battery on a charger to make sure it's fully charged.<br /><br />If you're new to boating, having someone familiar with boats/OB's come along for the first outing or two would help you ALOT. For example starting a big 2 stroke can take a bit of a "knack". <br /><br />I personally never feel completely comfortable about a motor until it's given me quite a few hours of trouble free service. <br /><br />Good luck,<br /><br />Brent

Your motor is a 2 stroke, and you must mix oil into the gasoline.<br />The motor is not oil injected.<br />Add 2.6 ounces of TC-W3 oil to each gallon of gas.<br />( or 16 ounces to each 6 gallons of gas)<br /><br />I repair manual will return its weight in gold.<br /><br />Make sure you do not remove the shift pivot screw when checking the lower unit lube. It is near the front of the lower unit. Very costly if removed.<br /><br />The drain screw is located near the bottom of the lower unit, on the side. The vent screw is about 6 inches above the prop shaft, usually directly above the drain screw.<br /><br />BF has good advice above.

Thanx, I'll be sure to do all that. The dealer I'm buying it from has already done the compression check and changedthe gear oil

Re: New(used) engine check-up, newbie boater

then you might ask about whether they've also serviced the water pump (changed impeller) or if they have a record of when it was last done (maybe they did the maintenance for the previous owner).... if they did do the work for the previous owner, I'd politely ask for photocopies of all the service records if they have them on hand. If they roll their eyes, offer to pay for the photocopying. Keep them, when/if you sell or trade your boat it helps to have some or all of the service history.<br /><br />Don't forget to ask for the owner's manual, but don't think it's a substitute for buying a service manual. Even if you don't do the work or maintenance yourself, you can see what's involved for labour and might get an idea if you're being ripped off when you need something done. Likely you'll see that maintenance things don't look too scary and you'll try doing them yourself.<br /><br />good luck & enjoy the boat!<br /><br />Brent

Yeah, I'll be doing the maintenance myself. I don't like other people messing with my cars/boat.
