1988 Mariner 200

That's nasty.

[Radeleur]

That's nasty.

Yeah, one place quoted me 3500 with 2 sleeves and a replacing the crank

[Radeleur]

#6 has pisst on scorring / cyl damage will require sleeve installation

What are you looking at in the #6 cylinder?

[JOE54]

see the marks on the chrome /bore in the cyls where the sides of piston alum has scored /rubbed against wall i may have a complete power head / engine after the first of the year for this engine of yours with no damage to cyls

helluva deal , is your crank bad though

I think I see what you are talking about...spent last 4 hours watching videos on youtube and pics....is it the 2 grey/white discolaration spots right by the ports on the left side of the pic? I will try to get better pics if needed

[Radeleur]

I'm pretty sure it is...with that said however, the other motor in my sig I have as well...and was thinking I could take the crank from it. The Mariner is in better condition from what my non-experienced self can ascertain. I know the boat the Mariner came on (the 88 Pantera 2) wasn't adultered/beaten...meaning as I am working on it, I am finding it has mostly all the original parts and etc...for exampled it still had the 1988 steering cable

I will attempt to get some pics

[JOE54]

yep and #6 has marks just about whole cyl any of those marks indicate metal being drug back and forth/scoring not good

[Radeleur]

1, 3, 5

[Radeleur]

2, 4, 6

[Radeleur]

Crank #3 cylinder bearing surface

[Radeleur]

I can try to take better pics....I notice several cylinders that have almost a milk white colored streak up and down in the cylinders (pics of cylinders 1, 3 and 4...4 really shows them)...not sure what it is indicative of. Also, had to break gray (the entire block and bolts are all the same gray) paint to take off the head bolts.

I can't get past the idea that you are willing to put any money into a 35 yr old motor.
If you spent crazy money on that pwhd, you still have a 35 yr old mid, trim, lower.
what am I missing?

Using that logic I should sell this motor, boat and my van and go invest north of 100k on new rig and boat right...

For starters: 1988 Mariner weight 358 lbs. 2023 Mercury 200 weight 475-511 lbs. 88 mariner paid off; 2023: approx 20k...I'd also say since it lasted 35 years to start that's impressive considering I know a ton of people who have already replaced powerheads several times on the newer motors...

We don't all have the luxury to go repower. Some of us work with what we have, can afford and are grateful we have that.

It's not logic. It's experience.
I was a mariner dealer in 88 and am very familiar with that motor, Still in the business have sold 2023 200's, There is no comparison between thoase motors.

[JOE54]

much simpler engine and far less to go wrong than the 4 strks, built in a simpler time yea that cranks bad you can find one cheap also

Could I use the one from my 86 Blackmax 200?

[JOE54]
