| 977.1 | Model???? | LAGUNA::MILLMAN_JA | I'D RATHER BE CRUISING | Mon Sep 12 1988 17:23 | 2 |
| You did not mention what make or model of pump you have...
|
| 977.2 | I THINK IT'S . . . | WILVAX::LANE | | Mon Sep 12 1988 17:49 | 12 |
| SORRY I CAN'T BE MORE SPECIFIC BUT . . .
I THINK IT'S A JABSCO. IT'S PUMPING RAW WATER TO A SINGLE CYLINDER
WESTERBEKE (PETTER) DIESEL. IT'S BELT DRIVEN, IMPELLER IS ABOUT 2" IN
DIAMETER OR LESS, HAS 1/4" I.D. INLET AND OUTLET, AND IS WHAT I CALL A
"STANDARD" PUMP. IT'S NOT ORIGINAL EQUIPMENT AS ORIGINAL WAS INTEGRAL
TO THE TRANSMISSION.
THANKS.

| 977.3 | Check the outlet | AKOV12::DJOHNSTON | | Mon Sep 12 1988 18:32 | 10 |
| Might not be the pump. Might be a blockage somewhere upstream from
the pump. Take the outlet hose off and turn the engine on. Be
prepared to get wet. If you get drenched then the pump is fine
and you have to look elsewhere. We had a similar problem and it
turned out to be a whole lot of eelgrass in the outlet hose. Jabsco
pumps are pretty hard to break.

| 977.4 | Hose connections? | YACHTS::CORKUM | I'd rather be sailing.... | Mon Sep 12 1988 18:54 | 9 |

Make sure the intake hoses are tightened securely as the pump will suck
air otherwise.

| 977.5 | hope this helps | LAGUNA::MILLMAN_JA | I'D RATHER BE CRUISING | Wed Sep 14 1988 13:22 | 12 |
| I would disconnect the output and again put the input into a bucket.
you can run the engine for a couple of minutes without any damage.
If the pump pumps then you know that there is blockage in the output
line (but if this was true, you would probable lose some of the
blades of the impeller). If the pump dosen't pump then it must
be the impeller or the hose.
hope you find it,

| 977.6 | Is it REALLY turning? | RAINBO::BURR | | Thu Sep 15 1988 18:38 | 7 |
| The impellor on some Jabsco pumps are attatched to the shaft with
a set screw rather than a flattened portion of the shaft. Check
that the impellor is in fact turning by removing the cover, releasing
compression on the engine and turning over the engine. Is the impellor
actually turning or just the drive belt?

| Check your seawater strainer. I cleaned mine once and didn't tighten
the cover wing nuts down snug enough. It allowed air into the system.
