Hey guys
I'll finish work early today and go start the seafarer for the first time. Apperantly its been sitting for around a year. It had a complete rebuilt and used only a couple of or so outing after rebuilt. It should be allright. The question is... should I use some hot water to soften the impeller? Thats what i read somewhere before...? I'll buy a new battery and some fresh fuel and give it a go... This post has been edited by boris: Apr 9 2008, 03:40 PM -------------------- Boris

Boris, we used to boil nylon propellers (for R.C. aircraft) to try and get then back to a flexible state. Impellers are rubber and I feel that if they harden, then no amount of hot water will change that state. If it pumps water then I would not bother. If it was rebuilt a year ago, then it should have received a new impeller. Try it, thats all you can do.

Impellor should be A OK & I definately would NOT be using hot water to soften it up
Reason I say this is simply heat expands things then cold contracts keep doing that & you'll crack even rubber used to make the impellor add to that that the rubber is bonded to a bush & you risk damaging that bond --------------------  Save The Fish, Eat a Pussy |

Yep Yep
Only way you can really check an impellor is to pull it out & do a visual inspection checking for cracks -------------------- Save The Fish, Eat a Pussy |

Boris. One thing I would suggest , if the engine hasn't been started for 12 months or more, well a couple of things,
Get a can of carby clean, take the plugs out and the air cleaner/filter off, open and jam the throttles fully open, and with a good battery connected, crank it over while squirting the carby cleaner down the throats of the carbys. Use about 1/2 a can of the stuff. Before cranking it over spray heaps of WD40/RP7 etc down each bore from the plug holes, use heaps, and even spray some more while the engine is cranking over. The engine will turn at a brisk pace with the plugs out, and the wd40 will loosen the piston rings and lubricate and clean any rust out of the bores. If you do this you will increase the reliability of the engine. This post has been edited by nimrod: Apr 9 2008, 08:06 PM -------------------- Frank

As long as the long term, the motor doesn't get too hot that you can't rest your elbow on it for a couple of seconds, at the side or top of the cowling, or too hot to touch with fingers on the side plate when the cowling is off. -------------------- Frank

Hmmmmmmmm Alarm bell not good @ all When you put it gear you would've droped the revs hence the QUOTE water stopped for a split second, came back again, and again and again... Now thermostat ??? Hmmmmmmmmm again It should not have any relevance to the alarm going off what I would do is pull out the thermostat then run motor again & get back to the thread -------------------- Save The Fish, Eat a Pussy |

Boris. ring the guy who's number is on the cowling and ask him does he have any records as to what work he has done on the motor.
You may have to pay him a search fee but he may be able to tell you a few things about the engine. -------------------- Frank
