Ryan and Kelly, Again I think there is no answer. It depends on the length of the voyage to the next opportunity to fill the tank, and this must take into account sea conditions and wind strength and

Jean-Pierre, Thanks! You and I both have older SM’s and the only manual I could find is for SM2000 which does not help much with the earlier ones! Mark

OK. If the switch is down, the pump should not run as the float ball/switch is at the bottom of the travel. The pump starts when the float ball/switch reaches the top of its stroke. Also, on the

Hi Mark, Let’s start at the beginning. Is the switch located in the cabinet containing the autopilot above the galley sinks? Also, please include the boat name, type and hull number. Cheers,

Jean-Pierre, Thanks. Is manual in the up position? As my switch is not labeled that I can see anyway. Best, Mark

Hi Mark, On my boat, the function is labeled AUTO or Manual. In MANUAL, the pump operates full time. In AUTO, the level switch activates the pump and empties the “sewer” until the level reaches

I tried searching for this, but couldn’t find the answer. My wife and I just returned to our boat and today I noticed that the bilge is running non-stop. I went to the engine room and noticed that

I replaced the original Onan pump with the Sherwood some years ago. It has a one piece casting instead of a detachable end plate. I thought its construction may help to extend the life of the

Mark, You're absolutely right, the Sherwood pump is the G702. It looks exactly like the one on the engine and some on-line sellers list the Onan part number with the Sherwood part

Bill R., Thank for your post. I actually had a rebuild kit on board (memory is an occasional thing for me these days it seems) and though easi-peasi, just rebuild the pump! But it will take a shop

Duane, I looked at your illustration. When water exits where you illustrated, the internal seal is leaking and the pump has to be rebuilt. I had 2 water pumps and switched them when the impeller

Barry, " Rubbish" , that was a bit harsh, all I suggested was to run it at a rpm that sounded good,in other words not laboring too hard, and then once in awhile run it a little harder to blow out

I would not do what Pat suggests, that’s rubbish. Kind regards Barry & Robyn Tradwinds III SM 171-- Kind Regards Barry Ferguson Email: seagasm@... Mobile/cell: +61 477 652 046 PO Box 1339 Hervey

Ryan , I have a Volvo TMD22A ,I also have a fixed prop for now,soon going to purchase a feathering prop, and I max out at 3100 rpm @ 8.3 kts., 2200 sounds good and gets me 6.5 kts. However max rpm on

You are going to all sorts of advise and as always, the opinion of the reply is always best. Troll around some 4x4 forums where you will obtain very good hints like install a catch can. Now, my own

Full throttle for us is 3000 rpm at 8knots when the bottom is shiny clean. Our normal cruise is 2000 at 6knots. Bumped up occasionally to 2800 to get things hot. Speeds are slower if it’s rough,
