so what DO I do....

[eupa]

Last Thursday , finally had my rib in the water at Nieuport ( Belgium)- after an extensive refit of practically everything -
Engines - all fuelines , tanks, filters clean, blown out, ect No work done on carbs as this was done last November.
Tubes - all cleaned and valves checked / valves taken off and tubes inspected for wear
Hull - scrapped and repainted
Electronics- all checked and Ok'd

So in the water at 1000 hrs. - ticking over like a watch - 15 minutes to the entrance at 1500 rpms/engine - still going like a dream then hit the outlet into a force 5 and we are off....... 10 minutes later and some 5 nms outside niewport -- both engines say good by!!!!!!!!!!!!!!!!!!!!!! They were running like a dream.....both primers firm and fuel coming to engines but not a sign of life. Eventually manged to get one engine going again but only for 10 minutes then stopped. Limped back into my berth using a paddle.............. I did get a cheer from some young things on the jetty.. but that was it.

All this is to advise people is to have some kind of back up engine. Next week will take all the carbs down .... and Yamaha and myself will probably part company. The engines have less than 150 hrs/piece and they have always being a source of problem- even when new.

In the meantime anubody have any ideas on what happened?? - remember they were going fantasically well for about 20 minutes
I will proably replace the yams with suzukies- thanks to codprawn.

You running twins? And did both die?......At the same time? Doesn't sound like engines to me but something common to both. You running water seperation filters?

Thanks - yes running 2*200 yams saltwater series counter rotating. Fuel system is in fact the Yamaha separation filter - i, e the water goes to the bottom of the plastic sight glass- and each engine has its own tank and arrival system. The second engine died within 3 minutes of the other. The only thing that i suspect is that when going into the rougher water the float needles could have jammed due to shit???- the fuel after the engine filter was pure.

Have you checked the tank breathers???

You reap what you deserve. Codprawn has a doll and he's stickin' pins into it.

Only common denominator between two engines with seperate fuel systems, must be the fuel itself. Was the fuel the old fuel that had been in the boat whilst being refitted? Either that or I'd be checking where I had refuelled. Sounds like water or other crap in the fuel. My 2 cents.

I reckon there is a virus or bug in the operating system - if he will stick with Mr Gates..........

And don't forget the electrical system ie: Isolater, battery and cables. Also check the ignition switch/s
