78 Merc 900 - trash it?

[S849]

I burnt a cylinder in my Merc 900 (90 hp). Dealer says it is probably not worth repairing. Is that consensus? I was offered $50 for it from a "junk" dealer. It has all the old controls and is very tough to replace the motor on this boat. Expert thoughts on my predicament?

Yes. Would have to be bored. To rough for a hone.

You might look around for a inline 6 with a bad bottom end for a doner engine

$50 is cheap. I routinely pay $200 to $250 for a dead core to part out - most people do.<br /><br />You do have options depending on how much you like this motor and want to save it. The dealer can't fix it economicly, but some indepandants could do it.<br /><br />A 115 powerhead is very (more) common and will bolt right up. If you price out a new 90hp Merc, your repair options look better and better.<br /><br />-W

I think this one is for sale. I don't think I want to mess with it. Don't have that much in it and not really interested in a lot more. This is hanging on a 16.5 ft. 78 Bonanza tri-hull on a Shorelander tilt trailer. Would I be stupid to accept $400 for the whole packaage?<br />Learning.. at a cost!

For *me* the boat/trailer makes it less valuable. But I think you'll get that much OK.<br /><br />-W
