There are three different types of gaskets available for dry joint elbows... Two for raw water cooled manifolds, and one for "fresh water" cooled manifolds. The difference is in cooling water flow...

I went from a 10+ gph burn at cruise to 7.5 gph burn ( with a 5 mph increase in cruise) when I went from a 185HP 283CID Engine ( 4.6L) to a 260 HP 5.7L. Both engines carbed.

There was a thread on the Volvo forum several years ago about "indexing" props on DP drives to minimize vibration.

Several issues....
1) I4 engine and V6 have drastically different front end mounting schemes..
2) I4 and V6 engines have different final reduction gear requirements, i.e. can't use the same "leg"...

My experience with an early push rod Volvo and milky oil. One day a very bad line squall dumped enough rain into my 18 ft runabout to allow water to rise above dip stick .... The marina...

Right... it's a inline. Inline exhaust ports sit a small amount higher off keel than V engines, but the physics the same... bow up.... dunk exhaust especially from boat wakes.

Bow up = stern ( and engine) down. The top of the exhaust loop in the "elbow" is a specific height by design above the "waterline'" ( boat level or running) to avoid this. Bow up on beach...

Is that the only electrical connection to the alternator???? ( other than 12 v neg via case)

Make idle adjustment with the throttle cable disconnected.... then reattach cable, adjusting it so it does not disturb the idle.

For maximum life and minimum "Boat Bucks" limit continuous RPMs, i.e. "Cruise" to 80% of the max RPMs you see with a half full tank and normal (for you) load in the boat in "calm" water. The...

Where is this fuse that you call the "ignition fuse" located???

Not necessarily.... from the picture it appears to be the correct module.... HOWEVER.... I never buy "Amazon special" parts for my boats... Stick with OEM or if you can't get OEM, Sierra makes...

That link is for the Delco EST system. It is a system that includes the whole pointless electronic ignition distributor. Your "Transpo-cn" refers to an aftermarket ignition control module. Is...

If it was my boat, I'd discard the stone filter, clean out bowl, reassemble.... install the unit below before fuel pump inlet. Mount securely to a bulkhead. Be sure to use USCG approved plumbing.

Again.. Thank you...

Thanks Dieter...

BTW.... is there an inspectable failure point on dry joint manifolds when removed from engine????

Are the hold down bolts P/N 10-864665 for the subject elbows reusable? My usual source is on Back Order and our sponsor apparently is out of stock as well.. Also source for the block off...

For sure the raw water pump impeller is toast. open it and find all the pieces of the impeller if the impeller is not intact.
The water temp gauge reads the temperature o f the water in the ...

If it's "Large" likely re circulation of cooling water in the block by the water pump, i.e. not the raw water pump... but as was said, without ANY engine info ?????
