Hi Guys, Just a quick question... Is the bracket in this photo standard? If so, what is it for? Thanks.  |

Correct, Wood. It supports the Centek muffler. Two large hose clamps go around the muffler and secure it to the support brace.

It was standard
And here's a nice clear picture from an old thread.

Thanks Guys. My boat never had those (since I have owned if for the last 15 years). I know the previous owner had to repair the muffler - maybe it was due to lack of these supports. But it has lasted 15 years...

So it has been a long time (off season) and the new engine build is complete  ... but
the engine builder just let me know that the "fuel pump cam drive needs to
be changed".  At the start of the build, I highlighted the new engine's blanked off fuel pump and queried the eccentric with the engine builder, but he said it was all good/compatible. But I now assume the eccentric was never fitted. What are the chances that the newly built engine (which seems like an older model, 70's era) needs a 1-piece eccentric? My old engine ('89) has a 2-piece. My options are: - 1) Buy and fit an low-pressure electric fuel pump? Then the timing cover doesn't have to be removed again. - 2) Remove the timing cover and fit a 1-pice eccentric? If that's what it needs. Can one easily tell from the cam gear whether a 1 or 2-piece eccentric is required? - 3) Remove my timing set from the '89 and fit it all to the new motor. What all needs to be refitted? Cam gear, crank gear, chain and eccentric? Any advise would be great! Thanks. |

You can use either a 1 piece or a 2 piece it doesn't matter as long as your chain and gears are compatible.
The cam doesn't care what kind of eccentric is hooked to it. A 2 piece eccentric uses a chain and gears compatible with it. Since your 89 has a 2 piece eccentric, maybe you got lucky and your new gears and chain are for a 2 piece eccentric.............or you could reuse the old chain and gears in a pinch if they're in good shape. Or an electric fuel pump and a low oil pressure cutout switch for safety reasons

Thanks Keno. I think the electric pump is going to be much simpler than striping the front cover off again. Looks like the Carter P4594 will work, and I'll get the oil pressure switch A68301. I just need to figure out if my existing fuel hose will work. I think it will. I have a Sierra 18-8115 with 5/8"-18 male inverted flare ends. The pump says 1/4-18 NPSF which I think is the same as the mechanical pump, where I used a brass elbow adapter. |

So the engine is finally back in the boat! Now time to do alignment and all the new wiring  |

Hi, I have everything installed, and the motor is running, but not very well.  Some notes on the current setup" - New Carter Electric fuel pump (with oil pressure switch) - Same Quick Fuel M600 Carb - New engine has a Performer Intake - The mechanic damaged the Pertronix ignition module (in my Prestolite distributor) by reverese polarity - he replaced it with a new one. The symptoms are: - Cold start, the idle is a lot lower RPM and rough. - If I give a little bit of throttle, it will give a large backfire out the carb and stall. - After several starts, (warm engine), the engine idles okay, idles faster. - Warm starts are fine.If I give a bit of throttle, the engine runs rough, but as rpm increases it becomes smooth. I have set timing to 6* BTC, and also tried 10* BTC (as per mechanics recommendation) Carb float levels are good. I have doubled checked the plug leads / firing order. Any ideas? My possible thoughts (based on similar issue I have read online) are: - Pertronix ignition module is faulty - Sticky intake valve - Vacuum leak - Clearance between rockers and aluminum valve covers? The heads are different - are they compatible with my aluminum valve covers? Thanks, Greg

Your picture shows a Pertronix module part #91281 looking like it's mounted to a pretty rusty old plate. That module and magnet ring are for a Ford Motorcraft distributor. Can't see enough of the rotor to know what it's for. The right kit for your Prestolite with a screwdown cap is a 91589 or the newer lobe sensing style kit that is 91581LS (there are also the cheaper 1589 and 1581LS versions). No magnetic ring is needed with the lobe sensing kits Maybe due to parts availability in South Africa somebody years ago did some clever adapting and made the 91281 work and the shop replaced the module with one just like it or maybe the shop did some adapting after they fried the old one and didn't get it right. Maybe it works just fine, maybe not. I guess you'd maybe know what parts were in it before the module got fried and what are new

Start with basics, make sure the fire order is correct and the wires are correct from the distributor to the spark plugs. You might have a couple switched or running a 302 fire order on a 351 engine. Some use 302 cams in the 351 and visa versa so your plug wire fire order must match the cam in your engine.

The 351 firing order used with a 302 cam, will give you an engine that's firing on 4 cylinders and runs pretty lousy, so if you didn't swap cams, a check of the cam's firing order is pretty easy to do. Use a 15/16ths socket on the harmonic balancer bolt and turn the engine by hand in it's normal direction of rotation to get #1 at TDC on the compression stroke. A finger over the plug hole feels the compression build up as you approach TDC. Now that #1 is at TDC on the compression stroke, put a finger over the #3 plug hole and turn the engine by hand 90 degrees and you should feel the pressure building up as it approaches TDC. If you feel the pressure, you have a 351 cam and the firing order is 1 3 7 2 6 5 4 8 If you felt no pressure buildup, put the engine back at TDC on the compression stroke for #1 and put a finger over the #5 plug hole and see if pressure builds up as you turn 90 degrees by hand. If you feel the pressure, you have a 302 cam in it and would need to rearrange your plug wires to give a firing order of 1 5 4 2 6 3 7 8, then all 8 cylinders will fire when they're supposed to. If that ends up being your problem, just say "Thanks MrMcD"

I would point the Thanks back to you Ken, that is a very nice write up on how to verify what cam type is in the engine.

Hi,
Been at the river with the boat with no reception. Managed to get it fixed by manually checking the cam timing. It has a 302 cam! Can't believe the engine builder didn't get the firing order correct. Now seeing your responses, you guys were spot on. I basically did exactly what Keno explained. Boat is running perfectly. Thank you all for your assistance over the last year. This forum is amazing. Completely blown away by the level of support you guys give. Cheers, Greg |

Good job
It probably means that the engine at some point had an "aftermarket higher performance than stock" cam put in it, so the boat just might run a little better........... maybe. Some were ground with the 351/late302 order and some were ground with the 260289/early 302 order and it causes problems like this at times. Here are links to a couple of recent examples of the same problem |
