finally got her in the water for the first time on Friday. I planned on it being a shake down run where I would learn all of her strengths and faults. I learned a couple things...
Everything started off well, got her launched, started right up, went through the no wake zone like it should. I started to give her throttle, planed her out and she started bogging down. Crap. I started doing the analysis...I checked the bulb, it didn't hold pressure when running...had my buddy keep pumping on it and the motor ran fine. Unfortunately for me, my buddy doesn't have the forearms of Popeye so I puttered back in to the launch and took her out. It's time to diagnose the problem. I am running off of a 6.6 gallon auxiliary tank at the moment. I haven't had the time to purchase a new fuel tank yet but I don't know if it could be undersized fuel lines from the aux tank... i dont know if my fuel pump is going on my motor, and I dont know if its my fuel filter or fuel/water separator. First things first, I will buy a new fuel/water separator filter, I'll buy a new secondary fuel filter and see what that does. Second, I'd like to purchase a new gas tank this week and hopefully get that in soon. That should help with the fuel line size issue. Thirdly, i'd like some help from this forum, do you think I should look into purchasing a new fuel pump or should I trouble shoot first? Any other ideas/opinions would be greatly appreciated.

Given the fact that the primer bulb got hard when the motor was off and got soft when it was running leads me to believe that not only should I replace the fuel filter, water separator and pump, but also pick up a new primer bulb... who knows if it has a bad valve... maybe i'll do the pump last so that I can return it if the issue is fixed with the filters and bulb -Brandon

at the shop I work at I heve seen many ( ATTWOOD) bulbs leek air and cause a loss in preasure. I recomend replacing the bulb and put a preasure tester in the output and see what you loose . but also always change the filter when any fuel suply work is done . JUST MY 2 cents

always use a primer bulb sold by an engine manufacture ie: merc/Bomb/yamaha/ Zuki.... The primer bulb will rarely stay hard while the engine is running, you have to overcome what the engine is pulling to get the bulb hard, and once its pulls that fuel, its starts to go down, you're keeping the bulb under vacuum. I would normally go straight to the low pressure pump, but they actually give very little trouble. Pull the pump off the valve cover with teh lines still connected and pump up the bulb, if you have fuel leaking past teh diaphragm, you know the pump is bad. Easy way to test the fuel system is to buy a fuel pressure test kit, they sell them at the auto parts stores for a reasonable price. One thing most people over look on Zukes are the high pressure fuel filter, its not cheap, so it rarely gets changed. If its like most of the engines i work on, the vapor separator tanks needs to be cleaned out, fuel screen needs replacing and then retest, if it still acts up, high pressure pump.

So now, I'll obviously for (maintenance purposes) switch out the water separator filter, fuel filter, VST screen, and fuel primer bulb and test the pressures in the fuel lines as I perform the work. If fuel leaks past the fuel pump when I pressure test the lines I will replace the $140 fuel pump, if not, i'll return it. I appreciate the help guys!

Finally got to tear into the motor. Varnish everywhere.... See below
What you're looking at is the fuel from the fuel rails in one cup and the fuel from the low pressure fuel filter in the other. The other pics are the Vapor Separation Tank and the Vapor Separator tank filter (new vs old). This is what happens when you dont winterize your motor or use stabil... I'm waiting on my High Pressure fuel filter and it should be testing time! Also tore off the old (OLD) Furuno depth finder and installed my new (to me) Humminbird 788 ci. If theres an interest in a working 1983 model Furuno, throw me an offer! haha Today i should also be attacking the compounding, polishing and waxing of the hull.

Got her out on Saturday afternoon and she runs BEAUTIFULLY!!!
I made it out to Lake Quinisigamond in Worchester, MA I spent about 8 hours on the water with 2 co-workers. Did some swimming, fishing, sight seeing and blasting up and down the lake. This is what its all about! I put 21 miles on the odometer and only burned through 4 gallons of fuel. I wasn't being nice on her either. I managed to clock in at 35.2 mph as my top speed. Not too shabby with the 115 on it with 3 grown men and a bunch of supplies. Didn't do much catching, but we had a blast in the process!
