So thermostats- I know my carbed engines came with 146 degree thermostats and the MPIs were 160. Why did they put such cold thermostats in these engines? Gas engines run more efficiently when they're a little warmer. Should I switch to 160 with closed cooling, or is there a good reason to stick with 146?

With closed cooling I would go with the warmer t-stat.

Ok so I bought thermostats for a 94 Chevy 454 and the flange is smaller than what was in the mercruiser housings... Is there another vehicle they correlate to or do I have to buy them for a mercruiser?

Don't know but the merc part really is not that expensive, how much do you want to waist guessing?

Trying my hardest. Have to balance family, though, and had an unexpected fiasco with my rental house...

Can anyone tell me what all these buttons do for the head? Top one turns on a vent, bottom pull out seems to be the shower sump. I still can't get the pumps for the toilet to work...

The metal ones don't look factory. My shower sump is a rocker like what's on your panel.

Is the sump just a little box with a pump inside it? There's also a pump under there that's an electric motor that drives a piston style pump. I think that's the raw water pump for the toilet. When I pull the lever and push the metal button, that pump starts in addition the what's inside the small plastic box. But the motor under the toilet itself still does nothing.
Time to start figuring these things out- hope to be in the water end of next week!

Shower drain will go to a box that has what looks like a bilge pump in it.

The other pump is a diaphram style and is used in bilge and fresh water pump applications.

Can you post a picture of it? Where does its hoses go?

The diaphragm pump looks like a hose that comes from the rear on port side that I thought is raw water, and the other the hose goes under the shower.

You really need to trace the exact place they are going otherwise we're all just guessing and cannot provide an accurate answer. I will say this is not factory.

The raw water pump for the head should be connected to a seacock. The drain for the shower would either go into a sump box with an internal float switch and pump, or it will go straight into a shower/bilge pump pump which will in-turn discharge through a through hull overboard.

If you have the latter style, there is typically a switch in the head which is required to operate it.

I've put a lot of time into the bottom- hope it's right! Second coat of paint early next week I hope.
Something I noticed though- water is seeping out of the tow loop on the bow. I looked in the chain locker and the floor in there is above the loop. Any ideas on why water would be coming out of there? I imagine the compartment floor under the forward berth is lower than that loop. Hope it's not leaking between layers of glass from the chain locker floor...

Looks like you used the old paint line so as long as you removed any loose paint or paint that was too think you will be fine.


Regarding the water I don't know but if water is seeping out that means the loops bedding has failed and water can also enter from wave action.

Did I miss something with the waterline? I sanded the entire bottom trying to get it as smooth as possible and remove the loose stuff. After I taped the top of the old bottom paint, I sanded that edge by hand, which resulted in a good bit of paint flaking off...

The nuts and backing plate for the D-Ring will be above the sole under the forward berth. Remove it, clean up the old caulk, then let it dry out for a few days, then rebed the D-ring again and you should be ok.
