Merc 115 Rebuild advice, $$$

[Broken_Bow]

Since replacement of my 80' 115 is cost prohibitive, I have to rebuild. I have the manual, tools, time (since it is broke), a few dollars and mechanical knowledge, everything but boat motors. LU is still good, power trim shot. Serial Number 5674934<br /><br />I have found a hole in the case just below the top carb which tells me that I threw a rod, or two. Compression tests show nothing in cyl 2, 3 but over 130 in cyl 4, 5. cyl 1, 6 unreachable as the power head is still mounted. Engine will still turn freely. My questions are.<br />1) Cost of a new/used crankcase cover?<br />2) Cost of a new/used crank?<br />3) Cost of a used block?<br />4) Motors that would be interchangeable?<br />5) Average resonable price for a powerhead (only) straight out of a boat, never rebuilt but running as well as can be expected.<br />6) Advice from anyone on the process, short of running away.<br /><br />Thank-You,<br />Paully

That motor is history.......You would want to get a matching case and cover which is big money. The other parts you need are big money too......In my opinion, you should be able to find another used running motor for a whole lot cheaper. In the dallas area, I have seen those straight six 115 go for around $1000 - $1200 in good running condition. You might want to search around for a motor with minor problems such as ignition or carbs. If your case was good, you would still be looking at $1000 to fix everything else. Try searching this board or search on Ebay. I think you will come out a whole lot cheaper buying a used good running motor. Good Luck...........

Agreed. And if you stick to the same model you'll have a bunch of spares....

I was affraid that would be the answer. What about #4 & 5? What powerheads could I use? Size and Year?<br />What about cost for a new head?<br /><br />Thanks for the reply.<br />Paully
