Wm, I'd agree with you that $350 is a lot of money
, no doubt you are buying
the "Authorized" sign on the wall of someone's shop. I don't know what you're paying for though.
To come to a boat, pull the injectors, take them back to the shop, put them on a proper test jig and observe the spray patterns and measure the flow, then adjust/clean and bring them back and reinstall, it could be a bargain.
To simply come to a boat, pull them and eyeball them, or eyeball the spray in a jar, it could be a lot.
Injectors will take a lot of abuse and work "forever", they just won't work optimally that way. A friend once asked me to tune up a car with an old Chrysler Slant Six engine in it, and two of the spark plug
tips had literally been consumed by the engine. With six new plugs it ran a whole lot better than it had been running on four.<G>
So by all means shop around, and as long as the engine is humming don't feel an URGENT need to jam money
into it...but I think you can see there are options, and you can probably pick one that compromises with your budget
This is also why I suggested getting a set of replacements
to swap in--which can be Gen-You-Whine New Yanmar, or often rebuilt injectors can be purchased for 1/2 the price
of new OEM ones. Then you don't need to wait, don't need the mechanic visits, you just need to check the procedure, do a swap, and send the old ones out at your leisure for a rebuild
, if it takes two weeks who cares? You'll still be running on the "new" set. And, if you do pull the injectors every 1000 hours for whatever reason, again, you'll always be able to swap and check at your leisure rather than lay up or be forced to use whatever talent is at hand. A set of injectors, pickled and sealed up whichever way you choose aren't going to corrode on the shelf, either. (Like anything else on a boat, you've got to keep the salt
