so what DO I do....

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.

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.

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

Ok this is it.

Carbs full of S**T. Compressions very low on 2 of the 6 cyclinders on each engine. Water in the lower parts .... you name it, I had it.... Will have to overhaul engines completely....
Ordered 2 *250 Yams HPDI 2-stoke effis. Be the fastest boy about town in two weeks. Very little delta in 200 vs 250. Got a deal from Yamaha in Belgium.
-15% off list.

If you're going to that expense, I'd have your fuel tanks drained 'cos it sounds like a dirty fuel problem to me.

As I learned to my cost last year, if you've got some poor fuel in the tanks, when you get towards the bottom of the tank in poor weather, it gets shaken up and overwhelms the filters.

If your boat has been left standing for a long time with some fuel in it, it may have been condensation that has caused the water problem.

I now try to leave my boat with full tanks for any extended period.

Nope the fuel going into the engines is "pure" tanks were drained and blowned out with CH3.OH - and on reflection the engines have been behaving on and off for some time. I know its a drastic measure but I need to rely on those engines 200%. What do i do if they give up the ghost in mid-atlantic?
Anyway what to do with money ? give it to my family? no way. Rather spend it while I can- and God said spend it, but give 10% to the poor..
