"Hi I would like to know two t

"Hi I would like to know two things,I have a V/P aq130c that has a small drip of water leaking out of the fresh water sea pump on to the fan belt. Is there a seal that can be installed or a rebuild kit avalible for this pump or would you be better off replaceing the pump? Please if someone knows of a after market pump replacement could you kindly post a link or two? My second question has to do with the fuel pump,I found at Napa a fuel pump that they say will work (part # NFP M60029) for about $60 however this pump has no thumb lever. Will this pump work and or fit? I had the boat out and when I gave it throttle it seem to bog down would'nt even plane,after about 3or4 min,it seemed to get more gas and rpms got to 4800 planed out nicely got up to around 30mph. Could this be from the fuel pump? Both carbs are rebuilt,new dip tube (gas tank),fuel lines and filter. But did not change the fuel pump or the metal lines to the carbs. It is old 1974 not to mention costly

All help is greatly apreaciated.....Thanks Walt"
 
"Walt,

Most likely you will

"Walt,

Most likely you will not have to replace your sea water pump, they do make replacement seals for them.Check volvopentastore.com or even this site for prices and availability. As far as the fuel pump goes napa shows it fits from 79-93 and you stated yours is a 74. Looks like the correct part but not 100% positive. Im glad however, at least you looked at a marine fuel pump and not a auto pump because you CANNOT put a automobile fuel pump in a marine environment.They get along the same as gas and water if you get my drift..."

As you see, you can get a couple of seals for around 20 bucks and the impeller (if in bad condition) could cost you around 25 bucks. It shouldn't be a big deal to fix your problem.


There is also a Sierra repair kit available, albeit almost as pricey as the original VP

"Thanks for that guys, I have

"Thanks for that guys, I have allways very much liked the quick response from the good peaple on this forum. El Pescador do you know if the link you sent me is the same pump thats on my engine? My pump has a "nipple" (for lack of a better term) on the cover wich the shaft fits into. I do not see that on the drawing.

This is what was on the boat when I got it. Perhaps it may not be origanl V/P I dont know? My concern is the shaft length. Do you know if this is the one that came with the 130c? Or perhaps the one in your link replaces this one? Will those seals fit this pump? Also, If I may, the fuel pump issue. I have an 8 horse kicker on the boat to limp back with, so I dont mind bypassing the thumb lever on the Napa fuel pump, and I like the price! Do you think this pump will fit and work with the 130c? Could you send a guy with lots of time but little money

a few links on after market parts for these two items? Three seventy five spent last weekend replaceing the drive bellows hose ouch!.......Thanks Walt"
 
"Walt, my AQ130C water pump wa

"Walt, my AQ130C water pump was replaced 4-5 years ago and it has the flat face like 10-35098-2 in the link El P. provided. However, I see one important difference in mine and that one...the mount points are like the Jabsco and Johnson."
 
"Re: the marine vs Napa fuel p

"Re: the marine vs Napa fuel pump.

It's not about the lever. That lever is only used when starting the engine after it has been off for a long time to fill the carb and save cranking the engine to do so. In the event that the engine has sat unused for a long time and the battery is low, it can be the difference between starting and not starting. It was discontinued on later models. Playing with the lever is unlikely to get you home in the event of a failure. You'd be better off paddling with your hands.

There are several parts on a marine engine that are "different" in order to meet Coast Guard SAFETY requirements. Among those parts: starter, distributor, alternator, fuel pump. Using an automotive part will put you at risk, AND should you be unfortnate enough to come up on the bad end of the odds, your insurance won't pay."
 
"Thanks again guys,still somew

"Thanks again guys,still somewhat confused,the Napa fuel pump is a marine one.What I would like to know is will it fit and perform correctly?"
 
"Sorry 'bout that. Folks

"Sorry 'bout that. Folks often post on this forum saying they are planning to use parts from NAPA and other sources that are NOT marine.
If the NAPA cross reference is correct and that part fits, then the lack of the primer lever should be little concern to you. As I indicated, you only use it to save cranking the engine to fill the carb. I used to have an AQ120 with the same feature and only used it once in 15 yrs... and that on a day that a rain squall came by when the boat was uncovered at the dock and the bilge pump ran an old battery very low."
 
"Thanks for replying Robert,no

"Thanks for replying Robert,no need to be sorry,I like and need all the help I can get.I was reading from another board I BOATS.com and a guy says all the old V/P 4 cyl use the same pump and this one from Napa should fit. I wanted to double check with the peaple on this forum as its the one I use most. I like that El Pescador fella He has much more knowlage than I, as do alot of others Bob D, Fast Jeff,Morton Ringwald your self and JHC just to mention a few.Still trying to figure out why my boat was so sluggish and would not plane till 3 or 4 min of full throttle seem to be a gas flow problem. The only thing I did not change with the fuel system is the pump and metal lines that feed the carbs.While doing research I found the Napa pump and I am guessing its less costly than the V/P pump.

"Re: "long time to plane.&

"Re: "long time to plane."

Some things to check:

1) Acceleration pump on carbs. You should see a good squirt of gas as the throttle is moved (Engine off)
2) Advance weights in distributor frozen and/or not moving freely.
3) Check Timing
4) Check Dwell (points gap)

It's possible to get a rough setting for 3 and 4 above with just a regular light bulb (or multimeter) and a feeler gauge. The procedure as I recall is in the owner's manual.

Of course, "EL" is going to say "Petronix" and if I still owned one of these engines, I'd install one. Seem to be well worth the price. All I remember is having to fiddle with the points on an all too regular basis "back then".

If you can get to 4800 and run there, it is unlikely a fuel pump problem.... however, if its the original pump, its getting elderly and you might consider replacing it as a precautionaly measure if your budget will allow. "
 
OK... that eliminates "4&#

OK... that eliminates "4"... If the weights are frozen "3" can still be an issue. "1" and "2" still on the table.
 
"I will double check point &#3

"I will double check point "1" acceleration pump this weekend as the boat is out at the lake waiting for a fisherman

as for point #2 the advance weights in the distributer??? Could you clarify what you mean I am no macanic and am trying to learn. Step 3 I think I can handle. What do these weights look like? How do you unfreze them? Do you think,as I do, if the fuel pump is from the 70,s its due to be changed anyway? Is there a filtering angent inside the fuel pump that could clog up? The boat did get up to 4800 rpm went like a banchee! And a good feeling it was! I dont know if the flow volume and cam lever are the same on the Napa pump as the years differ. But I did stay at a Holliday Inn last night! lol and I do know the owners of Volvo make Robin Hood look like a saint!.......Walt"
 
 
"Thanks a lot El, your a gem t

"Thanks a lot El, your a gem to this forum! What a great link! However what took that guy 4 hours will take me this winter, the "wallys" are starting to bite. As long as the boat goes faster than the pic swim.

The fuel pump delema 400 bucks for V/P, 60 bucks Napa,if I was sure it would fit, and perform as well as the origanal one, and the fact it just cost me 375 for the bellows hose

I was just looking to save a few green-backs..Do you think it will work?....Thanks again......Walt"
 
"Just a thought,would that be

"Just a thought,would that be 400 American or Canadian? add the shipping and tax's its closer to 5 hun. Kinda makes ya feel like your shopping in Sherwood Forest.

"There are some excellent shot

"There are some excellent shots of the advance weights in the link that "EL" provided. There is a quick test to see if the advance weights are frozen:

1) Remove cap.
2) Grasp rotor firmly between two fingers.
You should be able to rotate the rotor (with some moderate force) in the direction of normal distributor rotation about 30 degrees. When released, it should snap back freely."
 
"Walter, first of all the NAPA

"Walter, first of all the NAPA pump M60029 will not fit your engine. That pump is for the OHC engines, and it is the same animal as Sierra 18-7286

http://www.marineengine.com/newparts/part_details.php?pnum=SIE18-7286&returntopa ge=sierra_marine/sierra00811.htm

You are making the assumption that your pump is NG, but chances are the problem is a clogged strainer or a choked anti-syphon valve, or something else not related to the fuel pump.

Out of curiosity, what "bellows hose" did cost you $375?"
 
"The V/P Boat macanic charged

"The V/P Boat macanic charged me 375 to replace the drive bellows hose. I noticed one of the wire ribs pokeing out, so I pulled it and only one half was there. I never knew how (and still dont) to disconect the bottom end drive shaft that runs through it. As I said I am learning sometimes the hard way! So I had to take it in, You, and the peaple on this forum are a big help to me....so thanks again.....Walt"
