  1. If the engine is not running at all I doubt whether what they quoted you will fix it...of the list the carb rebuild is the most possible to correct a no start issue...but usually dirty carbs affect the way the boat runs not whether or not they start at all.....prices seem fair for the work quoted. Finally how would they know the water wasn't flowing if the engine wasn't running?
  2. Not really that much sand...just very minor amounts. The plungers are hard plastic about one inch in diameter. They run in a tube that is tight but not tight enough to seal all blow by (this is by design...its not designed to seal like a set of piston rings). Problem is the fine sand particles that blow through freeze up the plungers. The new design that dn0349 is the answer short of a new style thermostat that acts more like an auto thermostat...otherwise eliminating the cats would work too...don't know if there are techs that will/can do that. thanks for everyone's thoughts
  3. Took it to the place I purchased it...they acted like I didn't know what I was doing...I owned my last chaparral with a chev 350 for 20 years...same lake, same lot and boat lift area water skied in the same place and never had a problem. It gets to 3.6 ft at my lift....no way to back up and go forward without kicking up sand...even with the motor up half way. If you have ever seen the inner workings there are plunger thermostats feeding each cat...they are needed to keep the cat's hotter than the motor. Any piece of sand makes them hang up. The standard car thermostat for the block is just fine.
  4. I purchased a new 21ssi with a three hundred hp Volvo motor in 2012...we are on a lake with a sandy bottom and even when being careful the thermostats in the cat converters are getting sand in them....they then don't work and shut the motor down. This seems like a design problem. I understand the new gen motors now have a self contained water jacket with radiator fluid. is there a fix for this???
