To the right are two circular areas. These are bolts encrusted with salt. All bolts were dug out clean with a picking tool, air-blasted, and sprayed with WD-40:

Ah, the Virgin Miss Marco. Pure as the driven snow. Spent her life indoors.

Used only once.....to take his wife to church

That's funny - sorry to laugh at your expense but that old man was such a liar.  May he slow-simmer in hell with a job of replacing water pumps for eternity.

At least the good news is that everything that needed to be replaced was replaced and all the bolts and studs were loctited or coated with Mercury Perfect Seal, torqued and will come apart 5 years from now. Scotty got to see how these engines are put together and got a good education about how to do things right so when he gets them serviced in the future he'll know what the tech is talking about.

How long had these motors sat?  Most people would have used a BFH(big f-ing hammer) to get them loose and probably broke a few things in the process.. :x You guys did a great job of cleaning up the lower cases

[saltfly]

In one way you guys were lucky . At least you could get the power heads off. I’ve seen them so bad, you couldn’t get them off. The spline of the drive shaft was so corroded into the crank shift, that it wouldn’t come off. That’s why heat PB blaster and never seize have become my best friends when working on motors used in salt water.

Sorta like this?

Because of their past life do you think these motors would be a candidate for Mr Demeanor's vinegar in a drum treatment? I don't think it would hurt and could possibly get the water passages really cleaned out where you guys couldn't get to.

Link to Demeanor's thread, actually a really good read!

Glad you remembered that! SB says he has a tank

[RickK]

How were the thermostats?  I think the condition of them might give you a clue, along with the water pump, as to the condition of the insides of the engine.  Farley I think would agree unless he peeked already at that.

[seabob4]

Scotty, I NEED to get a tank!  List of things to do...

[gran398]

Farley mentioned the thermostat orifices were very clean. The water pump outer housings were nasty, but inside not too bad.

The powerheads were pretty damn clean.

Priced new 25" shaft twins today just for reference. Bombardier E-Tec 90's, $18,500.

Yamaha 25" four-stroke 90's, Suzy 25" 4 stroke 90's....around 17K, the Suzy's just a bit less.

Merc's were too heavy in 90 horse....380 pounds for two stroke, 402 for the four stroke (each).

The way Farley built them...Lord willing they'll be two chicken' eatin' babes  for a LONG time

Sure beats buying new ones right now. Try 'splainin' THAT to the wife

Hi Rick,

The powerheads were in very good shape considering the lower units. There was very little evidence of powerhead corrosion. When we took off the thermostat covers, the passages were considerably clean with a small amount of salt. The thermostats appearance wise were fine. There was very little if any salt in the exhaust tuner or powerhead base. A little corrosion on the stud nuts (brass). Very little carbon build up at the main exhaust opening. These engines didn't appear to have excessive hours, just neglect. I think these engines sat a lot. Someone had been tinkering the low speed mixture adjustment on the carbs because they were completely maladjusted too rich and too lean; I always check before tear down and compare to the base 1 1/2 turns out so the engine will start and idle reasonably. Also someone has got the timing and synchronization totally messed up. The side view of the timing arms in the photos are showing the timing at full advance against the stops with the throttle position at idle. Almost like someone had the timing arms off and the spring is in backwards. I really don't know how they ran at all. I'll be over at Bobs in the next couple of weeks to deal with that and get them fired up and adjusted.
