issues are all apparently now solved
..... the installation
of the new Yanmar
is complete and we conducted final sea trials yesterday. She runs great.
The process was not painless. The original estimate for the job was around $14,800.... the final bill was well over $17,500.
Lots went wrong. The transmission
that came with the engine did not fit. The coupling on the prop shaft did not fit when the transmission
was changed. At no point did anyone measure the engine space and compare that to the dimensions of the new engine package nor did anyone check into coupling specs before attempting to connect things.
Basically.... the Yanmar distributor says the dealer is supposed to ensure that all measurements are done and the new engine package ordered has all the correct parts
such as transmission and couplings.... the dealer says the distributor was supposed to do all that. All I know is I made sure everyone knew up front exactly what was coming out of the boat, including serial
numbers and that I wanted a new package that would fit the same footprint. That was apparently akin to putting together a shuttle launch in complexity.
So we had tons of extra time billed for swapping transmissions, fighting alignment issues and changing couplings and such.
The huge cost overruns stink. Had I known a repower
would have cost this much more I doubt I would have gone this route
and probably would have rebuilt the old engine. Still.... it is all over now and that is something.
Here is what I have learned and I hope others will learn from this as well:
1. Being a Yanmar dealer does not mean said dealer knows anything about Yanmar engines nor does it mean they are qualified to work on yours. Yanmar distributors will sign up anyone as a dealer. All that is required is a pulse.
2. Yanmar distributors are not the fountains of knowledge you would expect. In fact, they probably know less than you do or less than you will if you spend several hours reading about your engine.
3. NEVER spend a single
dollar on new engine parts
until extensive testing has PROVEN what is wrong with your engine. If the tech you are working with does not have the exact tools to conduct compression
tests, leak down tests and exhaust
back pressure tests.... you are working with an amateur and you need a new tech.
4. Yanmar has among the worst customer support on the planet. They apparently everything to their distributors and they do little to nothing to ensure that the distributor is held to any standard. So you may get excellent service
your may get run through the wringer.... either way Yanmar itself has nothing to do with it.
With 20/20 hindsight..... back when this nightmare began in January I should have gone back to the marina at Ortega and settled in to completely rebuild
my old engine myself. I should have torn the thing apart, jobbed out having the head
, turbo, injection pump and transmission rebuilt and replaced the pistons and rings while honing the cylinder walls myself. While this would have been a huge job.... I bet I would have been done much faster than 2 full months and I would have spent FAR less.
So that is what I learned.
