1995 Mercruiser 5.0LX 4 barrel carb
I noticed that my temp gauge never got more than a hair over 100 degrees. I just assumed the thermostat had been pulled. The boat runs great at all rpms but, when going from idle to full throttle the boat shutters or hesitates slightly. Almost like it is geting too much fuel. The plugs look good, cap and rotor too. The carb could use a rebuild being that it is 17+ but it runs too well for it to be a clogged carb.
I checked the thermostat housing and I was right about the thermostat being pulled. Made a phone call to marina and just picked up these parts:
All Quicksilver
27-41812 gasket
807252T 1 thermostat. 140 degree
23-47508T sleeve
The thermostat and sleeve had been yanked so I only have my manual to refer to. My Manual shows the sleeve having cutouts in it, but this one is a solid brass ring with on end rounded over and flattened. I installed the thermostat spring down with and the sleeve's rounded edge down.
I am concerned that the solid ring won't allow flow to the upper passages in the thermostat housing. My dealer said this ring phased out the old one. Anyone have experience with this?
Housing. Notice the ports at the top of the housing.
Brass Sleeve. No cutouts to allow flow to upper ports.
Here is how I installed them.
I really dont' want to get out on the lake and find out that I am starving a portion of the engine sufficient flow. Thanks in advance for any help you can provide.
