I ended up buying 8' of this stuff from Jamestown Distributors. https://www.jamestowndistributors.com/userportal/show_product.do?pid=12224 (SPR-750000810) It fits nicely using the recommended glass setting tape although it is not an exact match for the aluminum channel which was used on the port sid...

I was able to soften up the rubber seal on the plunger and the rubber cap on the bottom to get the pump to suck water up from the tank. For now it works well enough for my needs.

When I run out of other projects I will look into a pressurized water system.

pschauss

Any idea who made the original pump for the galley on the Sport Fisherman model? I would like to see if I could get the rubber parts to rebuild mine. Alternatively I would settle for something which would fit in the original hole in the counter top. http://www.ipernity.com/doc/307687/48876456 thanks,

My port engine has a Prestolite IDU 7801BS electronic distributor with a Sierra 18-5433 coil. The label on the coil says it needs an external resistor. With all of the wires connected and the ignition on I meshed 6 volts at the positive terminal on the coil. There are four wires connected to the pos...

Bob, How does that apply to 454s? I get about 23 knots at 3000 rpm and about 18 knots at 2500. The ride is comfortable throughout that speed range but this is the first power boat that I have owned (second season) so I don't have anything to compare it to. Am I putting more stress on the engines at ...

Is there supposed to be a drain plug somewhere on the tank so that I can get the water out in the fall?

pschauss

On my boat, it looks like the only way to fill the fresh water tank is to pull up the aft section of the cabin sole, unscrew the cap, and fill it directly. The only fittings that I see on the deck are for filling the gas tank and pumping out the holding tank. Am I missing anything?

Thanks,

pschauss

I have 454s but the distributors are not original and the port engine has a different distributor than the starboard engine. Based on the voltage I measured at the coil, the port engine appears to have an external ballast resistor while the starboard engine does not.

I came back from a 30 minutes test run this morning (ten minutes each way in the Connetquot River "no wake" zone and about ten minutes out to buoy 28 and back) and checked my ignition coils. Both were too hot to touch. Is this a problem? Both engines ran fine except that the port engine stalled twic...

Huh...old fuel filter. ...but if it were me. I'd remove from the line and stick with a single quality spin on and keep spare filter elements on hand, over having two separate in line filters.

Just found one on Ebay. It was made by Perko - part number 715B. FWIW, it's only the feed for my port engine. Apparently the one on the starboard side was removed when the previous owner's mechanic replaced the fuel line. https://www.ebay.com/itm/Perko-Marine-Fuel-Filter-and-Separator-288-1-289-1-LG...

I was hoping that someone would recognize it as a 70's vintage standard part. The exterior looks seriously corroded so I will try soaking it with Croil before I attempt to unscrew the top. If I have to apply any serious amount of force to remove the top, I will have to immobilize the body of the uni...

I found this in the fuel line which runs from my tank to the fuel pump about midway along the passage between the two engines. I assume that it is a filter/water separator as it seems to have a provision on the bottom for draining it. Is it redundant, since I have the spin-on fuel filters next to my...

On my port engine, the voltage at the + terminal of the coil is about five volts with the ignition on and engine off. On my starboard engine- different distributor - it is about twelve volts. My starboard engine has a ballasted coil. Based on the measurements I took it looks like I need an unballast...

I got half way across the bay this morning when my port engine quit on me. (It was the starboard engine last time, about a month ago.) By the time Seatow got me back into my slip, I was able to restart the engine so I am suspecting a problem with the coil or the electronic ignition module. The stick...

The sliding window on the starboard side of my boat has no seal where it overlaps the fixed glass pane. I have found a few sources for edge seal but they all want to sell it in 8’ lengths. Do you all know of any place which sells shorter pieces.

Mine are 21” at the point about one foot aft of the engine boxes and 24” at the middle of the transom.

Right now, I'm thinking it's and ignition problem (either the coil or the electronic ignition kit) since I was able restart the engine after it had cooled down for a couple of hours while I was waiting for Sea Tow.

Tony,

Mine are carbureted. It looks like I have separate pick ups for port and starboard.

I will check the automatic choke.

After looking at the boat this afternoon I am thinking that the noises I was hearing were coming from the loose parts of the cabinet work. After I brought my boat over from the yard I started work on removing the counter top and cabinet so that I could replace the rotten section of the sole undernea...

Last time I was out, my starboard engine cut out after running a few minutes at about 2500 rpm. Something was making a noise which I can only describe as a sort of metalic flapping noise. At that point it started loosing power. When I described the symptoms to the guy who runs my marina (a certified...

Thanks for all of the suggestions. I found some water finder paste at a local auto parts store and plan to check the tank this weekend.

I am running 454s with the Sierra 18-7945 fuel filters. If I have water in my tank would I expect to see water when I pull a filter and dump its contents or is the water trapped somewhere in the filter?

pschauss

I assume that you mean “coosa”. Is there some place in the New York metro area that sells it so that shipping cost won’t be so high?

I have the cabinets on the starboard side detached now so that I can move the unit and access the sole on that side. What is the best material to use to replace the existing plywood?

pschauss

Are those cockpit shades available off the shelf or were they all custom made?

pschauss

After all of the references to trolling valves in this thread I looked up to see how they work. If I understand the description correctly, they work by effectively letting the clutch in the transmission slip. Doesn't that put premature wear on the system?

I have had my share of electrical and ignition problems with my two British cars but none that I ever traced back to spark plugs. Whatever the case, the plugs that are in my 454s now are NGK BR6FS and they worked fine last summer so that is what I will be replacing them with. Distributor caps and ro...

FWIW, I have been putting Champions in my MG and my Healey for 20 + years and never had a problem with them.

The plugs in there now are NGK BR6FS which cross references to an MR43T. MR41T cross references to R5673-8 which is a hotter plug with a shorter reach (11 mm vs 11.6). Since the engines ran all right with the BR6FS plugs I will stick with them.

I have only had my boat for one season and she certainly would not win any awards for fashion but everywhere I went with her last summer people knew what she was. My favorite comment was from a guy waiting his turn at the gas dock in Oakdale who said to his companions: "Now there's a REAL boat."

pschauss

What plugs should I be using? The MR41Ts that the manual recommends have , apparently, been discontinued.

If you run three outboards with port and starboard rotating in opposite directions, won't the one in the middle make the boat steer to one side?

Tony, Based on your comments it does sound like my boat originally had the Thunderbolt system and it was replaced by the Prestolite and Mallory systems. As of November when I put the boat in the yard, both engines were running satisfactorily so I have no immediate plan to change the ignition systems...

pschauss

Here is one reference that I found for a 1977 using a Mallory.

https://forums.iboats.com/forum/engine- ... 330-please

pschauss

Thanks. So It looks like at some point someone likely replaced the Thunderbolt systems with the Mallory and Prestolite and added the electronic conversion kits.

FWIW, when I googled the topic, I found references to use of both Mallory and Prestolite mechanical distributors on early 454s.

pschauss

Any idea which, if either, of these distributors (Mallory or Prestolite) was original? The Mallory uses an electronic insert from Sierra (18-5296-2). The insert in the Prestolite looks like part # JMS-65-189 on this page: http://www.marineparts.com/mpf/mpf884.aspx .

pschauss

Any idea what distributors were originally used on the B31s with 454s (1978)? My starboard engine has what looks like a Mallory with an aftermarket electronic conversion kit. The distributor for the port engine has a label on it which says "Prestolite", also electronic ignition. Everything is inside...

I assume that you know about MSSI numbers and the automatic distress signal function on these sets.
