The seals I use run $32.00 per set. As far as labor, you are looking at 5-6 hours per side to pull the engine and drive. The labor to pull the exhaust, valve covers, swap the springs, retainers, seals and locks, adjust the valves and replace the covers and exhaust should run about 5-6 hours per engine. Total for a twin engine should run 20-24 hours of labor, plus parts. Hope this helps. Eddie |
I was not including removing the heads. There is no need to remove them if you are just changing the springs. If it needs a valve job, then obviously the heads will need to be removed.

You should be more concerned with the quality of the mechanic performing the service than the cost ...cheap , unqualified labor always bites you in the ass later .

It usually creates more problems in the end but not always i guess.. |

Sounds like it will be around $1,600 (20 hours @ $65 per hour + parts). If you're mechanically inclined at all, I would take the heads off yourself, drop them off at the machine shop, and pay the mechanic to put everything back together. It should save you about 1/2...

5-6 hours a side to pull engine and drive and reinstall seems a bit high. I guess that is a fair estimate but I would expect it to take less time than that depending on the room available in the engine compartment.

By the way, my shop rate is only $65/hr. That's not an excuse to charge more hours, just stating my rate, as most are at $90+/hr. |
It took me 10 hours yesterday to pull 2 engines start to finish on stands and hatch back on. And I'd done these many times. I'd think on a boat that is unfamiliar to you it would take much longer.
If you have more than about 200hrs on those engines I would certainly opt for pulling the heads and doing a valve job at the same time. The incremental expense will be minimal. |
