The marina replaced the impeller, lower unit pump and thermostat on the boat
yesterday. Out of 12 blades on the impeller, 3 were totally gone, 3 were
half gone and the remainder had cuts and nicks on the ends. This was not
damage that happened in one day but it certainly caused my overheating on
July 1st.

If the marina replaced the impeller when I asked them to earlier this season
I would never have had the overheating problem. I will let them slide on
this one but will make sure it the impeller is replaced every 2 years in
spring prior to launch. No sense monkeying around with a $40 part.

After I installed the VHF radio and antenna on the boat today I took it out
for a test run. It runs good and the temperature did not go above 155 even
at WOT or low idle. So far it looks like the engine or risers did not
suffer any damage and I may have dodged a bullet this time.

With sunny skies and temperatures in the 80's forecast for this weekend,
combined with light southerly winds (meaning a flat Lake) we will be on the
boat both Saturday and Sunday. My daughter came home for the weekend and
will be joining us, making it even more special.

Maybe our string of bad luck has ended.......most likely due to good Karma
according to some. ;-)

JimH,
I am glad the boat problem was minor and you will have a great weekend
with the family. A weekend with the family can put all other of life's
minor upsets in the proper perceptive. Enjoy.

That's my story and I am sticking to it!

Wonder if they ever charged you for that service they didn't perform?

Good show, Jim.

well, that's one hassle out of the way.

What was causing the rough running? Or, did they say?

The overheating itself caused it, at least according to them.

Nope. And I found out how the "diagnosed" the impeller to come to the
conclusion I did not need to replace it................they ran the engine
for an hour, including a spin out on the Lake and watched the temperature
gauge.

I am only going to use these guys for basic maintenance and repair, and I
will be replacing the impeller myself in the future just before Spring
launch. I no longer have any confidence in their mechanical abilities.

As a side note.........my Volvo repair manual says the engine takes a 160F
thermostat and that is what I installed in spring.

The mechanic who worked on my boat says it takes a 140F thermostat and that
is what he installed.

The engine is a 1997 Volvo Penta 4.3L with an SX outdrive.

Will running the wrong thermostat temp have a negative effect on the
engine's performance?

Glad to hear that things are looking up, Jim......

Thanks Gene. ;-)

Ok. Pre combustion "dieseling". That makes sense. I'm glad there
wasn't any further damage due to the over heat.

No name-calling for 24 hours and his luck is changing already!

Glad it wasn't serious, but I'd sure be looking at replacing the manifolds
and risers before it becomes something serious in a boat nigh on ten years
old.

John, you just cannot be nice, can you? What is it like living with a
