it seems that most people out there do not know what they are selling. i am finding it very common. i have had people give me the wrong year ... some off by as much as 10 years ..

That's right on par for the course . . . Welcome to my world. You'll learn to ask the right questions and save yourself the gas money and time.

ok .. here are some numbers ..

one the top freeze plug C139606

on the carburetor 1374-5427-0 or C then WH these numbers are on the top of the carbs

There are more numbers on the carbs . . . the carbs on C's are funny. The numbers aren't next to the "wh-". I'm almost 100% sure it's a 2.0L . . . I don't think merc made a 2.4L 150 in 89 except for the XR4 which I think was only 88. I don't have my book here, but I'd bet you it's a 2.0L. Did you buy it?

i am waiting to make an offer until i know what it is for sure..

the other thing is i would like to check compression .. there are no wires with the motor ...


not sure where i can hook up the battery to spin it over .. as i have said before, this is my first boat project .. if it was a car, i would be ok.

i do not want to screw up anything trying to spin it over.

can you give me details on how to check compression? .. i have a gauge.

what else should i be looking for?

he told me that he just had to replacing something electrical on the motor .. his friend turned the battery switch to off on the boat when they were out .. when they ran the motor to get back home, something fried on the electrical side. not sure what it was, but he said he paid a lot of $$ to fix.

bsteckel - www.google.com or www.screamandfly.com or www.byuboyz.com or pickup a Manual. I'm not typing out how to do a compression test on an outboard.

thanks for the help.

will search on another board.

IT"S ABOUT TIME!

bsteckel: For someone with lots of "car" experince I find it difficult to believe some mechanical knowledge isn't easily tranfer to an outboard? We are all working this hobby on a budget, but with outboard it has been my experince you get what you pay for. If you want to learn, buy a junker and dig in and go for it. There's nothing like hands on experince. At this point I'm not sure what anyone else could tell you - JUST DO IT and get it over with!

thanks guys for the support. it seems on this board if you have not been lurking here for 20 years, then you are not worth of asking questions. i understand how many would think i have been dragging on about my outboard purchase, and you are right. i have had some issues where my motor budget got cut in half, so i am really trying to make sure i do not get burnt financially and get the best bang for my buck.

i searched this site for info on doing a compression test .. did not get much back. i know nothing about outboard electrical, charging, wiring, systems ... but i am sure if i do something wrong, it will cost money.

kamikaze .. not sure what your budget is and i really do not care. obviously you have not paid for something and gotten taken or you would not make such a stupid comment. sometimes you do not get what you pay for. maybe you can afford that, but i cannot. and sorry i do not have the years of boating experience you have. this is my fist project boat .. i can send you pics of the car i built in my garage and if you want to come see it, your are more than welcome. i just do not dive into things and get my hands dirty. that can become costly .. i try to arm myself with as much info as possible .. if this annoys you, sorry .. dont read my posts. i am sure some of the car stuff will transfer, but with all the wealth of info here, why would i not ask? not sure how a car motor would be real similar to a 2 stroke outboard, but if you say so .... also not sure how my car experience would tell me if the motor i was looking at was a 2.0, 2.4, 2.5 merc .. thought i would ask someone that works on these daily. i have done compression tests on cars, but the wiring was there and i turned the key to crank them .. this outboard is a little different. do not want to fry a relay, burn up the starter/wiring, etc.

BS has been a huge help with all of his posts, and so has FERM. A few others have also chimed in and i thank you for that ..

maybe i am too much a newbie for this site????

hope i did not overreact here .. i did have a stressful week at work.
