Our boat also has a little trouble starting after it has been run and stopped for 10-15 minutes or so. It cranks fine, but sometimes takes a few extra cranks to actually fire. The fuel pump is next to the exhaust down low in the bilge and I'll bet it gets quite hot down there. The heat might even cause it to draw a little extra power and blow a marginal fuse. I'm going to get a temp gauge and monitor the temps. A small thermostatically activated fan might help extend the life of the pump. My experience has been heat causes most of my repair issues.

Stoneman - when did your fuse blow? Was is after you had been running awhile?

I thought the fuel pump cooler was actually there to cool the return line fuel to prevent the lower pressure return line from getting vapor lock, not to cool the pump. The high pressure side won't vapor lock.

A 350 cid GM motor is a small block.

Try emailing the eBay seller "kandkmarine" if he has any more of the pumps. I got a spare for $158.

Hmmm, I wonder if running the blower would help then? I almost never use mine, but I really don't have any vents going into the engine compartment on my boat. It gets in through various gaps in the sides of the boat. I'll try and see if running the blower for a while fixes this. The problem is that the thing is soooo darn loud.

I think I'm going to not mess around here. I am going to get the entire assembly and replace it, plus I'm going to replace the anti-siphon valve. I have another trip with the boat coming up in 2 weeks, certainly don't want to be sidelined then too.

Is that 350 considered a big block or a small block?

Also, anyone know what size that anti-siphon valve is? 3/8? 1/4? (1997 PRE2150 w/t)

The 350 is a GM small block 5.7 Liter.

The part number I got was #861156A03....I will research and see what the (04) number works with. Maybe it is a newer version......thanks for the fuel pump link,,that is the cheapest I have seen the pump kit....

dogbert - I had thought of using the blower, but our pickup is on the other side of the motor and probably wouldn't help any. Our blower is the original blue plastic 3" cheapo, but it's not very loud. Also, now that you mention it there are no intake air vents on these boats. My old boat had a dedicated scoop on the side for fresh air. Cool air must be coming in thru all the gaps in the engine housing. One of those gaps takes all the water that comes over the nose - had 1/2" of water pour thru there a couple weeks ago.

350 cubic inches = 5.7 liters (approx), English vs metric

[dogbert]

Ok, we both have essentially the same boat. My blower pickup is on the driver's side. Is the fuel pump on the passenger side?

[R&T Babich]

Just the opposite. The blower is on the left side of the boat and the fuel pump is on the right (drivers side). Ours has the 350 Mag MPI. The raw water pickup is in front of the fuel pump/cooler on the right. The fuel filter and trans cooler are on the left.

A 350 is classified as a small block. Anything under a 400 is classified as a small block. JLEDGER. Give me some part numbers PM them. I have access to all the Quick Silver Line and Merc Cruiser. I can try to see if I can find them for you at a decent pricing. And I understand why you were at the lake last week it was hot in Minneapolis. I though of contacting you

Allen,,
do you know if that pump is the newest version part number of 861156A03???

[Stoneman]

Babich-the fuse blew after we'd been running for about 15 minutes or so close to WOT and it was about 120+ that day. Could be the heat??

My boat uses the part ending in 04. Check the TSB I linked earlier and match it up with your engine serial # on the side.

Here is the link to your model 861156A03

I ordered mine yesterday. The guy @ boatfix told me a little about the product #'s. The letter (A) at the end of the part number means it comes in plain cardboard boxing. If it had a Q it means it would come in a quicksilver box. The number at the end of the product number is the consecutive number of the vender used to make it. Thats why the original part # has a 1 at the end and the others on that TSB are 02/03/04.

How much did it cost you. I found a place where I can get them for $240.00 + Freight.

[TeamAllen]

Thanks anhaney. I paid $248.02 + $10 shipping. Maybe your connection will help out one of the others.
Thanks again for sharing!
