This girl i have been dating has a 24' pontoon...it has a 1992 Johnson Sea Pro 115 on it. the guy she bought it from said that about 3 years ago(been sittin up)said that the oil mixing unit went bad and they bypassed it....when they bypassed it the guy didnt mix the oil in the gas tank. Ofcourse bam, spit, sputter, load it and leave it sitting....said that it started smoking before it died. Had compression check and it wont hold compression and that the lug was flattened in the cylinder.

I am not that familiar with them other than runinng them and doing maintenance as you should including adding oil to the reservoir...LOL. She is wanting to fix the boat up and have a decent summer toy....

is the motor worth the repair or do you think based on that information she is going to come out cheaper trying to purchase a used/rebuilt motor? is there anyone that you know that is retired or mechanically inclined that doesnt charge the boat places rates for labor that could run disgnostics and possibly fix it. Right now it is on blocks but I do have access for a trailer than it can be brought somewhere.

what if it isnt worth the repair expense would be a good place to look for rebuilt motor. It seems the steering cables and throttle cables are ok and not seized up....

I doubt you can fix it cheap. That oil you put in the gas lubes the rod bearings, wrist pins, and rings so it's probably rernt.

$1500-$3000 depending on who you take it to. Call several reputable dealers & get some quotes.

It sounds to me that you have probably got some scrap aluminum there. I would have a Mech look at it before I scrapped it though. There is a guy in New Hope that sells used outboards. He also repairs them for the public without charging 65.00 per hour. I know another guy that lives near Guntersville dam that works on them. He is a good christian man that I would trust. PM me if you want names and #s.

Most of the time with a motor that old it's best to junk it and buy a used motor. I had a pontoon with a 35hp Mariner I bought pretty cheap. Paid $1700 for the boat and put $1200 in that little motor before it got right. I learned an expensive lesson with that one.

I have a '94 90hp that I just found out has a broken ring that has scarred one cylinder pretty bad.
In order to have it bored out and fixed properly(including rebuilding cards, changing impeller, etc....) I am looking at $1700.
So, I have a choice, get it fixed, or have a 24' pontoon boat that sits in my yard. Comparing NADA prices... a pontoon w/o a motor vs. with is about that much of a difference.. So I am hoping to look at it as an investment. (ha ha)

She should be able to get a "rebuilt" or used power head for about a grand, maybe a little less. Nothing to swapping them out. disconnecting and reconnecting the wires and levers is more trouble than swapping the "head" out.

updated....friend of mine has a buddy that does outboard repair part time retired.

He would pull the heads for $50 and be able to see from there if it could be rebuilt or not.....if it can be rebuilt.

rebuilding the whole motor said he wouldnt do just 1 cylinder it was all or nothing because of warranty work and future problems with other cylinders for $2200.00 if the power head was good....if power head was bad then looking at a total of $4000.

He has a 94 Evindrude Looper 120hp that he wants $2500 for it installed using the levers, steering from her motor now. If the lower unit will swap between the 2 he will sell the 94' model for $2000 installed.

what are your thoughts on 2 year 5 hp upgrade opposed to potentially not being able to be rebuilt, or getting in with rebuild then power head bad and having $4K TIED UP

^^^

Ding ding ding! Winner!

Claims the purchase seems to be best scenario I see myself.

anywhere else anyone knows of to look for a good rebuilt or used motor?

You might try "I Shop Marine" I ask them and they said there were two different power heads for 1992 Johnson. They had both, one for 1650 and the other for 1450(rebuilt). A New one, all ready run in by them, was like 2300.
