New here with a 1992 90hp

[floatfisher]

Bought a boat a little less than a month ago, a 1992 Spectrum 1706 with a 90 horse Force. I took the boat out for its maiden voyage yesterday with the family and could not get the motor to start I have heard the motor run 2 times before, once when I bought the boat and once when I changed the plugs. I am sure they had the motor warmed up nicely when I got there the day I bought it and the motor started right up. The second time I started it up with not a lot of hassel after changing the plugs. There has to be a "trick" to starting all motors and maybe I just need to figure out the "trick"?

The boat has a built in gas tank and I am not sure how big it is but I put in 6gallons of ethenol free high test gas and mixed it with the 50:1 mixture. I can not get the primer bulb firm?!?! Should I pull the vent tube and see if there is a blockage in the tube from the side of the boat to the tank? I loosened the fill cap and got a little pressure in the bulb but still could not get the motor to start!

I am not a motor guy or mechanic, but I dont mind working on stuff if I know how. I just dont know much of anything about boat motors. My last motor (a 89 25hp Merc tiller) ran fine for years so I didnt have to learn much about it.

Any help would be appreciated!!!

If the primer bulb won't get firm and there is no fuel leaking out of the carbs, the bulb is at fault.

I don't know what kind of fuel hose you have or what the fittings are like, but on my 30 horse Evinrude, the fittings on each end of the hose are identical and the bulb has an arrow on it indicating the direction of fuel flow. It is entirely possible to connect the hose backwards, that is with the arrow pointing towards the tank instead of towards the engine. That will cause the motor to not start and the bulb will not pump up either. The remedy is, of course, to remove the hose and install it the proper direction. I won't tell you how I know this, but I can assure you that the guy who does it usually feels pretty stupid when he realizes what the problem is.

I just realized that you said you have a built in gas tank. I doubt if anything I said would apply to you.
