You can also get magnets on a telescoping rod. YSM8 doesnt have a sump pan. Pushrods are easy to hammer straight, bent one of those as well squirting engine oil
in the air intake to get compression
up but its done 75 hrs since I hammered it straight ( only a slight bend). I've reused my head gasket
2x using Loctite 515 flange sealant
. If you want aftermarket parts
PM me. I hope you havent got a junked piston coz they are eye-wateringly expensive from the Yanmar
mafia if you must have genuine.Done most mechanical stuff on our YSM8 which is pretty close to your YSE8 so can answer most questions you may have
Thanks! I have seen that the piston is over $350, I sure hope the head is not caved from a valve... Yikes.. Is it the case that there are many aftermarket parts
for this engine? I really hate to have to order everything from a Yanmar Dealer at top price
and wait for a week or more while paying exorbitant shipping
to boot (and I surely don't want to have to go without if the dealer channels run out of something for this engine that has not been made in over 30 years).
I really would like to build a spares kit at some point, for things that are typically at risk, pushrods, valves, keepers, springs, any problematic gaskets, water
pump impeller, etc., but I am told Yanmar never created a rebuild
kit (which is what I REALLY do want, as I am about to tear this engine down in a few days and am concerned about if I find worn things here or there). I can tear it down farther if I know that I can get bearings, seals
, etc., and it will make me more comfortable to know that I can reassemble it with proper tolerances (weak links created when installing new parts elsewhere, such as these springs, etc..).
I have located a dealer in Green Cove Springs, FL (near me, sorta) who can order the springs in (talked to him late yesterday evening) and they are about 4 bucks and change apiece. We discussed the engine, and he tells me that aside from this sort of issue, the engines are "bulletproof" (not the first time I have heard that adjective in relation to this engine).
He told me to tear it down, inventory what is needed, and then come to him with a list. That way the exorbitant shipping
cost is not applied to each part as he has to order it in.
I would definitely like to know what sorts of aftermarket options are out there, because the springs at even $5 each, plus the $16 shipping to him, plus the gas to get to him (maybe $20), and then the additional order fees
, and then multiplying things by additional parts (say, pushrod, tappets, injector pieces, etc.) will get costly in a hurry, if I need all that.
I am still hoping for the loss of compression
caused by the open valve halted the engine!
Still, if I need more parts, you will be the first call!
I already replaced the starter and alternator
(starter was literally gone
, ie. missing
, and the alternator
was corroded to the point of wire absence at key contact points internally, and was little more than a poor anchor
for the dingy).
The GCS dealer told me the repower
for this vessel is a 20HP engine that uses a 100 amp alternator for all the 12V goodies that cruisers want, but we laughed and discussed how it would never be a recovered or even amortized cost, as it is about $6,000 for that engine. The boat just is not worth the expense. I could purchase
a larger hole in the water
for that, and apply my efforts at that one instead of this one.
Not that a 20 HP would get this ~7200 lb dry weight sailboat above hull speed
but would likely shove the stem underwater instead, in my truly unqualified opinion. Perhaps loading would change that, but I don't know that this hull
could plane, and I don't know that my kicker
mount would survive the encounter with a 20 HP outboard
Still a larger inboard could perhaps lope along at mid idle for better fuel
economy and less wear? Regardless, I am not doing that. If the inboard dies and I cannot effect major repairs
for $250 or replace it for under a boat unit, the engine space is going to become a fuel
and spares locker for perhaps a larger than 8 HP outboard
(or maybe for the same 8 HP I currently own).
boat for heavens sakes...
Hey, that would be a great place to store... SAILS!!
