What I did was take a normal rotating pump and used the parts out of it. The shaft on mine broke so had the old shaft stub pressed out of the old impeller and the shaft of the normal rotation pump presse out then repressed on the contra impeller. put all back together and works great. If the...

For me my max speed is 8K which is good for wahoo, kings, and dolphin here in florida. If I start catching bonita just need to drop back about 100 to 200 RPM's.

A lot of Gulfstars out there. Thanks.

Got the same boat. Good group on https://www.facebook.com/groups/gulfstarboats/

Wow, hard to believe a small water expansion tank would cost more that the heat exchanger. Think I'll go with the bargian $495 one. Thanks all.

Normally I don't respond the these things but seems these two lines explains everything.:blush:

The tank is on the side of the engine with the heat exchanger attached to it.

Opps, I call the engine coolant with antifreeze the fresh water side. You are talking fresh water as in a lake. Then you are looking for Magnesium Anodes.

I'm looking for a water tank that my heat exchanger fits into. Perkins 6.354 1971 with heat exchanger part number NA001545. Don't know the part number for the tank. Found refurbished one for $495 which seems high. Anyone have one laying around?

Should only have the pencils on the raw water side. The antifreeze protects the fresh water side.

I just replaced mine with the garmin 740s combo package. 18 NM high def. radar. Radar is line of sight so depends how high you are mounting it.

1972 Perkins 6.354s Zincs on raw water side of the heat exchangers. Had to replace heat exchangers due to PO's neglect on the zincs.

I am in Florida and I keep my tanks full just in case. (may need a quick get away. lol) I have a single 300 gallon fiberglass tank which should have less condensation and have never had any problems. As far as weight at haul out don't worry about it the yard takes that into account and if...

There is a facebook Gulfstar owners group that is pretty active. http://www.facebook.com/groups/gulfstarboats/

Well no such luck. It was a normal rotation pump. I am just going to buy the rebuild kit for the normal rotation which will work on the contra. NAPA has them since this engine was used in combines. When cruising out of the US it's the parts that are expensive not the labor.

Just left a message for carter D. Thanks.

VERY interested. Should be part number U5MW0114. Just left a message for carter D. Thanks.

For what it is worth this is the part number of the contra pump. U5MW0114.

Totally different. Top is normal rotation with impeller out, right is contra pump.

And side by side. sorry don't have a pic with the impeller out of the contra. Wish I had taken one now. Contra on the left. Of course when on the engine the bottom of the picture is the top of the pump on the engine.

Here is the normal rotation pump or what is left of it since had to take the shaft out to repair the contra.

Here is what the contra pump looks like.

Hopefully for you it is a normal rotation engine and you can get parts from NAPA for massey-ferguston. Caseing and impeller are the only things different on the contra. I'm pretty sure the went to normal rotation when the borg-warner velvet drives came out. I've been in the bilge so much...

I had planned to do the same trip but everyone I have talked with said it took about two years round trip. No fun if you can't stop and smell the roses. I'm heading out from Florida in April to the Bahamas and south. I haven't decided if we are going to try Rio or the Panama canal and to the...
