Tired of being passed

Don't put the risers on before the valve covers. Can't get to one of the cover bolts. Now the dipstick won't wort.

Sizing of the heat exchanger is done by the heat rejection rating of the engine.If you want to double check, someone should be able to give you a figure for the engine in BTU's. You can then match it to the heat exchanger specks. Believe it or not in my experience the biggest issue here is a raw water pump that pumps too much. Doesnt let the water absorb the heat or something. We've actually have put washers in the overboard discharge pipe to restrict the flow. Doesnt sound like there will be an issue here.

I went with the dipstick that swings out to the front of the engine

Port side dipstick.

Mines on Stbd side. My records show this Mercruiser part number 15296A2. But I dont have the hockey puck on the end.

Final assembly

more, finally done. Will go in boat on Monday.

Very nice. Where did you get those exhaust risers? Are they 3"? I like those better then my standard Mercruiser ones.

Fredwarner,net. Bought a few parts from them. Same day shipping for free.

Looks good Jerry. Great talking to you today. I’ll reach out next week.

Finally, in the boat. I was surprised at how much room there is to work on this engine. I can reach everything. Other SBs in 26'ers that I looked at had no space between the gutter and manifold.

Have the cooling system all put together but, It is just to make sure everything will fit. I can't find any 1 3/4" 90* fittings. Have it mocked up with PVC but they won't work with 200* temps. Any reason not to use galvanized pipe fittings?

[crhodes]

Where are these 1-3/4 fittings going? Yea, fresh water is going to get 200 degrees but few raw water side places get that hot. I recently purchased, at a hardware store, some plastic fittings that are rated for either 200 or 250 degrees. (I too used them in a mockup.) Point being a high temp plastic might be enough if in a lower temp and safe place if it fails.

Regarding galvanized, again it depends where it is going. Not as good as bronze but you may have to settle

What exactly are you looking for.. Threaded both ends, hose both ends, or something in between?

[Quik Fix]

Need to connect the fresh water hoses. From heat exchanger to the expansion tank and expansion tank to thermostat neck.. Need 2 90* elbows. 1 1/2" galvanized pipe screws into the hoses nicely.

[Quik Fix]

Redid the FW side with galvanized elbows. 1 3/4" hose system but no 1 3/4" fittings anywhere.1 1/4" pipe goes in and tightens down. No leaks. Like the way I've relocated the trim pump, batteries and HE. This engine is easy to service. I can get my chubby hands on everything.
