    update:overheating at idle

    OK I thought it was fixed but it appears it is not.i just went to the lake yesterday and still doing the same thing. getting hot on idle but now my gauge is working. so i am watching the temp gauge and it will be running at 160 and then just jump up to 220 then just go right back down to 160. it will just keep doing this every 60-90 seconds like clockwork. heat up cool down. i am puzzeled so i get the boat home and i am thinking maybe the shop put in the wrong t-stat or some thing. so i remove the housing and find that the shop put the t-stat under the lower housing instead of on top where it should go. and to add to that the t-stat looks about 2 years old and they did not use any gaskets only rtv sealent and man did they gob on the sealent it was just overflowing the inside and out of the housing. and they wondered were all of this blockage was coming from. i am sure it was peices of rtv coming of now and going into the manifolds.My question for you is do you think the shop should reemburse me for repairs? since they clearly only coused me problems instead of fixing them. also should tige' require its dealers to have certified mechanics working on there boats becouse i dont believe they are. for them to make this mistake is pretty crazy.

    just got of the phone with the owner of the shop and he wants me to bring it back so they can fix it would you?

    Ok, that sounds like a bad sending unit or gauge. The engines actual temp cant fluctuate from 160 to 220 in 1.5 mins.

        i could also feel the manifolds getting hot as gauge went up and cooling down when gauge went down i guess motor just cant circulate correctly when parts are installed wrong

                Having the thermostat installed incorrectly in that housing will not cause the boat to overheat. What it will do is cause the heater to work better at idle and the exhaust manifolds to run cooler.

                  there is a reason it is installed in the upper housing and not in the intake manifold directly. The t-stat will not open correctly becouse there is cold water on top of it with hot water below so they are conflicting with each other and will not let the t-stat open and when it does finally open the cold water makes it shut right away causing the gauge to go up and down.I dont Know all the details for the passage ways in the housings but what i do know is they put the t-stat in the upper housing for a reason and if you install it wrong your boat will not cool correctly. and it makes for very weird symptoms. i know this because that is what my boat was doing.
                  why i was mainly writing this post was to get your opinion if you would take your boat back to a shop that used rtv instaed of gaskets and did not install parts corectly.the owner wants me to bring the boat back to them so they can fix it right and all i want is my money back for what i paid them to do the work so i can take it to a pcm certified shop.

                      I would ask for my money back and take it else where.
