|Has anyone had any experience using a belt driven ballast pump that runs off of the boat engine? (attached to the engine and powered like an alternator) |
Jasco makes a few that have pretty interesting specs: light weight, 25-60 GPM @10 ft of head, self priming, remotely actuated electric clutch, etc. Let me know what you think...
Here's the manufacuter's website:
Here's a dealer for prices:
|Was thinking just the same thought the other day. Infact a standard inboard engine driven water pump will fill a system pretty fast!|
|what about using the exsisting impeller to empty the sacs? If you could watch the bags and idle in it seems like a good idea. anyone with experience?|
|i tried using the impeller pump on the first system i built back in like '99. the problem is that flow is determined by the engine thermostat, so it's unpredictable. i never tried interrupting the raw intake & just pulling from the sacks, but it seems like that would work. would have to be very careful not to run the impeller & engine dry once the sacks are empty, though. |
also, i'd love to see a ballast system using an engine driven pump with an electric clutch. i just don't want to be the one coughing up $600 for the pump...

|I t'd my water intake and use a reversible simer|
|i think Rob was asking about using the existing engine cooling raw water impeller pump, right? |
FWIW, i have two parallel Simers pulling from a T in my raw water line as well. this system works best for me, after trying several different approaches.
|Just making a point that it is easy to tap into. Not to get off the subject, but did you cover your simer pump with anything to keep towels, etc. off of it or where did you mount yours. thanks|
What is a "simer"?
this is a pic of mine, which are mounted under the back seat of my VLX. basically they're in their own little box.
|very cool. thanks|
|nice system! I envy your mechanical know how!|
