impeller

Hi All, We have our new to us 400 sedan bridge 2000 since last season, and I am planning to change all impellers at launch in spring. During the mechanic inspection/survey last summer, the cat mechanic show me how easy it was to access the impeller and change it on the cat 3126 (well access on...

Looking for some advise on replacing the impeller on my port 3116 Cat in my 1999 370 AC The boat has just been put on the hard for the season. I closed seacock valves for both port and STBD engine. Removed the strainer lid for the STBD engine and poured antifreeze into the strainer with the...

I am happier knowing that my pick-up is in the water, unobstructed. I've only had outboards with very visible telltales (piss-holes) before. An impeller rides in an oval cavity and the volume of the wedge shaped segments are diminished as it rotates to create pressure. The lobes are deformed by...

I want to drain the coolant from both engines. I am looking for some suggestions on what else you would do if you are spending the time and money to do the change and flush. Impellers would be an example. Would you look at changing the impellers if you were unsure the last time they were...

I have a 2004 Sea Ray 220 Select with a Mercruiser 5.0 MPI Bravo 3 engine. I am attempting to replace my impeller but seem to be having a difficult time figuring out how to get to the thing. Do I need to remove one of the idler pulleys to get to the hoses to disconnect the inlet and outlet...

I have a 2005 Sea Ray 270 Amberjack with 496 Mercruiser Mag engine. I recently replaced the raw water pump. Now I have a small hose coming off the top of the pump (above the air fittings) that is not connected to anything. I don't remember disconnecting it and don't see any place for it to...

Need to find raw water impeller model for 1986 340 Sedan Bridge with Cusader 454. Would like to have two on hand before removing old ones.

Hi all, I recently took my boat for warranty work to change the drive coupler so they had to haul out the motor and leg. In doing so, they discovered a small mussel in the water pump assembly so they said it had to be serviced and recommended that I change the impeller. I had it changed about a...

I own an '06 SeaRay 340 DA that is equipped with a 5KW Kohler Gasoline powered auxiliary generator installed aft of the starboard engine. I recently had to change the impeller, and in the course of doing so found the old impeller had broken up. Since the new one was installed however, even...

Hey guys, Although, I've piloted many boats for some years, from parents to co-owned boats, this is my first solely owned boat, so I'm a little new to boat maintenance. I'm getting ready to do my first (of many, i'm sure) impeller replacement to hopefully solve a water flow issue I am having...

I started winterizing, but wasn't aware hose was kinked somewhere, so overheated really quickly. Impeller is in pieces. So now I need to backflush system to remove these- before I can replace impeller and start all over again. Can I do this (flush) by inserting a garden hose to the port side...

How do I replace the water pump impellers on my 2005 Sea Ray Sundancer 360 with 8.1 Merc Horizons?

Love this forum--thank you to all the boat techies that take the time to write down their solutions... Now that we've had our new to us Sea Ray 340 for a couple of months, it was time to start the monthly maintenance drill. Our 2006 Sea Ray has a wonderful set of Yanmar diesels to push her...

Ok, so I just had my 320 shipped from MO to TX. The dealership that I bought it through serviced both engines (changed impellers), etc. When I first got it in the water and ran it, the cooling hose came off of port engine, smartcraft alarm went off after the the temp got up to 180ish and the...

When you replace the impeller in an Alpha 1 gen 1 drive, do you usually replace both the housing and the base or just the plastic housing? I see most kits do not include the base. It has two oil seals in it. Do they come installed in the base" Any recommendations on brands - Sierra, GLM...

Went to Martha's Vineyard for dinner. It was just a normal night on the island... until we were ready to come home. We tried to strategically leave before dark (around 7:30pm). Untied the lines, left the dock, and we were underway. Just got past the breakwater, ready to accelerate to get out...

Hello all! I'm a new member here so please be patient with my post. I have an 1989 Sea Ray BR200, 4.3LX with a Gen I Mercruiser outdrive. I recently had an overheat condition at low speed. She got hot enought to sound the alarm. I put her in neutral and increased the water flow and brought...

Hello All, Thanks in advance for any troubleshooting advice.... I bought a 2003 260 Sundancer last year and had a lot of trouble with overheating. A lot of things were tinkered with by a mechanic last year but eventually we decided it was a temperamental thermostat, because the problem...
