GTB Marine will ID your housing, modify it and install the temp safe system.
It is not recommended.
Threading the housing on center and to the right depth is very important for proper fit and movement. This is why modification is included in the price.
When you get your housing back it will have a new thermostat, new gaskets, washers and sealer for install.
Depends on if you live local or not.
If you live local I will pick up and drop off and it will only take a couple of days.
Out of town - 8-10 days
