Generator Exhaust

[34Hatt]

Dan remember his business is.....


Those bad additives cost him money.

Oh yeah now I understand


Don't worry though I going to give him some business this winter.
Since we are giving him the Business now
Looking to clean up the generator that's the only thing that makes some soot
Derek said we will start with the injectors.

I could be wrong but thought most of the time you reply that additives are not needed?

And you really didn't believe in them?

You're thinking of some other exspurt.

IMO the the gens soot more because they are subject to instantaneous loading and unloading as pumps ,ac units ,etc cycle on and off. I prefer the side exhaust for a SF because the exhaust is less likely to get caught in the stationwagon effect when your trolling and running. When drift fishing you can lay the boat so the gen exhust goes downwind and forward. Yeah the side hull gets that black mustash but its better than getting the party sick from the fumes.

One of my previous boats (a 41 Egg Harbor sportfish) had the generator exhaust plumbed out the transom. It was not located within the main exhaust but had it's own separate small diameter exhaust pipe which exited under the dive platform. There was never a problem getting any water going up that exhaust pipe.

The down side to that design is if you like to anchor out and swim or hang out off the stern of the boat that exhaust is right in your face. On my Hatt it exits out the side which is much better when you are swimming off the stern. The soot on the side is very minimal and only requires occassional cleaning. Guess like most things there are plus and minus.

Re-ferbed my 74, 45C in 07. Installed a "GEN-SEP" above the Vernalift. They seperate the water and exhaust. Water leaves under the waterline and exhaust is VERY quiet. One of the best changes I have ever made to my HATTY. I have owned this boat for 23 years. I know what you are dealing with.

Interesting so it is quieter than before?

From the Centek site

The Gen-Sep™ is used in conjunction with a Vernalift muffler on generator sets. The water drain from the Gen-Sep™ can be located below the water line to eliminate irritating water splash during overnight moorings.

I don't get that splash noise since it is inside my exhaust pipe!

I never hear the generator exhaust. I have a 7.5 MDJE in a sound shield that drown that out

So how do you confirm you are pumping water if it discharges below the WL?

 

[Fanfare]

On my waterlift muffler I can see the water discharge. But if my raw water pump fails I can immediately hear the difference--no "muffle" at all. Even before the high temp alarm sounds. The impellor usually destroys itself on startup. That's why I always start from the salon. Sounds like a chainsaw.

Any soot above the waterline with a "GEN-SEP" above the Vernalift???.
