[Rhodes22-list] Motor report.

[Lowe, Rob]

Rummy,
That's pretty good record.  Note that your repairs had nothing to do with 4 vs. 2 stroke.  You just happen to have a heck of a good motor.

I finished repairing my 2003 Yamaha 4 stoke motor last week.  It came with my new(er) boat but had been sitting on the hard for three years.  I rebuilt the carburetor and water pump as a precautionary measures and both needed it.  The carb was all gunked up and a good cleaning and rebuild fixed it and the water pump had sand(!) in it and a rebuild was needed.  The vane had started to deteriorate at this point.  About $75 in parts at this point.  I believe I reported that my lower unit leaked oil when filled and was filled with the same milky stuff you described when I drained it.  Over my pay grade as this point so I took it to a mechanic would said it appeared the seal around the shift lever had gotten dislodged, possibly by having water freeze in the unit.  Either that or mechanic malfunction (me).  I'm blaming in on the freezing water.  Anyway, he charged me $75 for his trouble.  

What was really surprising was to find the prop was all bent up and had to be replaced.  I guess the PO had run aground somewhere, which probably explains the sand in the water pump.  Probably sucked it in when he hit sand.  Another $80 for the prop.  

So I've got it all together and started it in my driveway using earmuffs to provide cooling water.  Now water is just spitting out the pee hole instead of a good steady stream.  I'm wondering about the water pump job at the moment and if I need to take it apart and revisit it.  Instead, I pull off that water discharge line from the fitting in the case and it runs fine.  This is also the first time I realize the water pump is also the fuel pump.  Interesting.  I guess there are two water pumps?  The one that is on the lower unit and one part of the fuel pump?  Anyway, I find a pipe cleaner and clean out the pee hole.  Damn mud dobbers have been at work.  Now the motor is peeing as it should.  I declare motor fit for service!

So I'm out about $230 at this point and have a well running motor.  

I think my point is anyone with the right skills and tools and a very good parts diagram or service manual can do basic maintenance and repairs on their motors.  But I'm like you, I'm leaving the lower units to the experts.  - rob

The list members are always being asked which are the best motors for the R22. I am sad to report that after 19 years of perfect service I am finally having to do some repairs on my 1993 Tohatsu 8 hp two stroker. The fuel pump  failed so I got a repair kit and fixed it. Then I changed the foot oil and found  it to be milky so I'm having to replace the seals on the lower unit. As long as  I'm taking it apart I'm going to replace the water pump for the first time. I'm  also replacing the fuel line and hand pump. Total cost of parts about $150.00.  Not bad for nineteen years of perfect service. This is why I like the two  stroker over the heavier and quieter four strokes. I can actually do the repairs  myself. The local Tohatsu dealer quoted me a price of just over $325.00 to do  the work. I figure I will have an additional
$175.00 for rum.
 
Rummy
