Evinrude 15034-07302 needs work

[hnkogan]

Hello,
I have recently purchased the 57' aluminum boat with a 18HP Evinrude. The model/serial #'s on it are: 15034-07302.
I ahve no clue what year it is or anything else about it.
1. I do not know what mix does it run on. Is it the same as the other small engine? There is no manual. Does it need oil?(separate from fuel addiditive)? Where?

2. The motor starts and smokes a lot. I assume it needs at least a complete tune-up.
I have very little experience with gas motors, none with boat motors. I do want to do all the work myself, however. I want to know my way around it.
Please give me advice! Where do I start? What to look for? Any good on line supplier of parts? (I live in the tri-state NYC area, everything is very expensive here).
Thank you very much!
Hana

hnkogan,welcome to the forum.
Can you double check your numbers, 15034 crosses to an electric trolling motor.
Maybe you could post some pictures.
There are a lot of people here that are willing to help and ansewer questions for you.

Thanks!
I just checked my numbers. They are correct.
I do not think this thing is a trolling motor, It is 4 ft tall and comes on a stand. Inside are the same two numbers and then also: 304781.
I also checked on line and found that 15034 is a 61' 18 HP electric start. This one is equipped with electric start hook up, no electric start assembly.
I will post pictures today!

You are correct, the reference I was looking at didn't go that far back.
1) You need to mix oil with the gas, ratio of 24:1, and yes it will smoke.
2) Lots of parts still availabe for it. With some TLC that engine will last you a life time. Make sure the water pump is in good shape, maybe replace the impeller, keep the lower unit oil clean, use fresh gas and keep it tuned properly. I would suggest you get a factory service manual for it, try E-Bay or google KEN COOK, they have factory manuals.
There are a lot of people here to ansewer questions for you if needed.

Thanks!!!
1. What grade gas? 87 OK? What additive? Regular 24:1 rated for small engines?
2. I looked up manuals. They have:Ower's man; Service man; parts manual. All 3 cost in exess of $100 plus shipping!
Since I am pretty sure I will need parts anyhow, I would wait to order all in one place? At least save on shipping? But do I need all 3?
3. How do I see the water pump is in what shape?
"keep the lower unit oil clean" means there are two units(at least) to be oiled. What are they?
Is the 'impeller' a winged wheel in the bottom that takes the water up to the pump? How do I know it is bad?
Looking forward to hear more info!
THANKS TONS!!!

I understand that both fuel lines have to be replaced.
Also carburator rebuilt.
The rotor in the bottom is not in a new condition, onviously, but seems like still workable?
Some places are so dirty, I can not see a thing. What could it be cleaned with?
Thanks!!!

1) 87 octane is OK, make sure and use oil for marine engines.
2) Get the service manual, you can look up parts at marineengine.com for free.
3) I guess I should have said if you are sure the water pump impeller has not been replaced in the last couple of years, replace it. It is part of regular maintaince to replace the impeller every couple of years depending on use. The lower unit oil should be checked a couple of times a year to check for water and changed in the fall to make sure it doesn't have any water in it to freeze in colder climates. After you have run the engine for a while you will get an idea of the water coming from the exhaust discharge on the exhaust housing, if it appears to be showing less water, you need to check the water pump. With normal maintaince you should not have any problems.

Thank you!
I am reading the instructions on tune-up. The flywheel removal is lengthy and messy, but I assume I have to remove it, as the motor is old and probably had no maintanance in ages. Am I right?
Also, If anyone is kind enough to look at the pics and let me know if there is something obviously wrong already outside..
Thanks!!

Re: Evinrude 15034-07302 needs work

Thanks to all for help!
1. The flywheel is off and here are the pictures. This looks fine to me, so I do not know if I should change some of these, all, or nothing!
2. I can't remove the carb from it! The tutorial I have found for 10hp Evinrude has a slightly different configuration. In my unit the screw that holds the "governor"(?) is facing the motor, as in last two pictures. I just can't get there with the screwdriver! Help!

1) Looks like one of the coils has been replaced already, clean the points and make sure the gap is correct (.020).
2) If you are talking about the linkage that the roller that advances the carb linkage, just remove the clip on the linkage that comes up from the carb.

Re: Evinrude 15034-07302 needs work

Thank you!
1.What are the points and the gap??? (This is my second look inside ANY small motor. The first one was an old logsplitter motor that I have burned...) The lt green coils is new. Should I replace the other one?
2.Yes, I am talking about this link. Could not remove the clip, it was on the shaft inserted through the body of the carb. Took needle pliers and unscrewed that from the side. Have no clue how to put it back.
Here is the open carb:


I am wary of destroying the calibrator cover. The carb is very clean, I think I can clean it well without removing it?
Obviously, the gaskets and the float have to be replaced. Anything else?
Thanks!
