I'm going to be installing a Blaxland 3.5hp with a closed cooling system in my 14" Putt Putt and wondered what other people had done to muffle the exhaused system. |

I take it you are going to use bilge cooling to cool down the coolant? In this case I would suggest that you install another water pump to draw in sea water so that it can be passed through a water trap muffler and exhausted by the exhuast gases.
If you are using sea water to cool the coolant then the egress point of the sea water could be diverted through the water trap |

Julian,
I raised this issue back in about Nov. '04 and there was quite a discussion c/w some photographs of others nice set ups. I have completed my closed circuit cooling, run the Blaxland twin out of the water with a squash plate hydraulic pump hooked onto the prop shaft to load it up. Never looked like getting too hot just by hosing the keel cooling tube over a 1/2hr run. Have rigged a small Jabsco to put external water into the muffler, believe it is putting in too much judging by the amount blowing out. Will alter the pump pulley size and try again one day. |

Thanks for all the advise Seadog and Rosey. What I'm really looking at doing is having a dry exhaust with a muffler and just wondering if anyone has tried this before. What I either propose doing is cutting the standard wet muffler box in half and having a S bend of perforated tube fitted inside and then packed with steel wool, just like a standard muffler or having a custom made muffler created by a guy I know who makes mufflers for Formula Fords. Has any one has tryed something similar to this and if so what have your experiances been? I'm trying to get away from having any sea water entering the engine/muffler at all. |

Lister made an air cooled engine(s) for marine applications. Bearing in mind no sea water ran through the engine it would be safe to say no water came out of the exhuast. It may be worth trying to get hold of detials about air cooled marine engines and have alook at thier muffler design???? |

Julian, I have used a Vinco with a dry exhaust but it was fitted with a small marine muffler to cut down on noise. I have also had Pilot and Wing air cooled 4 stroke motors. These came with a dry muffler (about 6 inches long and about 5 inches in diameter. These were finned (for cooling) and hollow. When using an exhaust pipe through the side we used to wrap it with asbestos cord and use an asbestos packing piece around the pipe to stop the pipe burning the timber. They were not as wuite as a water cooled exhaust but quite acceptable. rod. |

Gentlemen,
It's been a while since I've been in touch; nevertheless, I'm alive and well.
At this time, I'm wondering if there's anyone out there can help me with the same old problem I'm having with the ignitor of my 4-atlantic engine.The tripper(within the binder) keeps wearing the hole bigger, thus causing the engine to fail to work . I have no way of mending it at this time. Regards,
Ray Johnson |
