    Good one!

    I see Jabsco on it.... send it to me, and I'll go through it for him.

    If this tank modification could be done, and done safely, this is more along the lines of what I was thinking.

    A small section modified only, in order to maintain as much capacity as possible, yet give good access to the crankshaft pump.

    Without a doubt the tank can be modified,a qualified welder knows how to do this. Not all welders want to but Ive had tanks moded several times without a prob finding a welder to do it.Buying or building a new tank could also be considered....Pretty well any option is better than what is there now.

    The other option is to replace the fuel tank altogether, instead of getting it modified. Moeller has a HUGE variety of tanks that might work. Sure, you'll lose some capacity, but it is a small price to pay given the alternative. The only drawback I can see would be if the tank is built into the hull and glassed over, which might make it a royal pain to remove. Once the tank is out, the possibilities are endless. He could even consider two tanks.

    #2 he finding some one willing.to do it and that is qualified.

    Dangerous.... I agree, it sure can be...., but be smart about it.

    The right person will know how to purge the fuel vapors from the tank. Some will fill the tank with water, tilt it as needed, and purge with an inert gas only at the area where the work is to take place.

    This is right up there with my Dodge minivan I had where the intake manifold had to be removed to change the spark plugs. It would have been easy to make the manifold go the other direction to allow access. I don't think its job security as the newer ones arent, designed that way. I worked for Chevrolet for 15years long enough to know some engineers are dumb asses.

    Any way there are mountings that can be used to change the water pump position. I have them on my boat and have been dealing with it recently.

    Here is the problem.... probably all the accessories up front will need to be relocated and theIcooling system plumbing modofied. My sea water pump has the alternator on the same mounting bracket. Which is on the right side of the engine facing the front of it.

    Not every thing can be on the same side. Most likely the power steering will have to be relocated to the other side. There are mountings for that.

    As for the gas tank. A couple of things any one who welds on a fuel tank that has been filled is going to live a short life. Yeah yeah I know its been done but still not too smart.

    I cut apart a fuel oil tank last summer and even after having it full of water and hadn't had any thing in it for many years it was still rumbling when I cut it open.

    The other problem.with modifying the tank is that all marine tanks are supposed to be coast guard approved certified and pressure tested. Im not sure that it would be worth it. Also may have an insurance issue if not certified.

    There are plenty of boats out there with side mount pumps it will just need some home work.

    Gary, just as Ed did, when I saw the engine for the first time, I thought feul tank mod!

    I wonder if it would be feasible to remove the engine one last time. I know.... I know.... yuck! rod

    Pull the fuel tank, and have someone who knows how to purge one and make the modifications to it.

    However, I have no clue as to access in removing this fuel tank.

    Is that possible with the engine removed..., or is there much more involved with this hull?

    Personally, I'd have the gas tank modified. It could make up for the cost of pulling the engine every time.
    Man, talk about thinking outside the box! Great one.

    My 5.7L Mercs have belt driven seawater pumps.

    The crankshaft pump makes perfect sense, but sucks in this scenario.

    A belt driven pump doesn't really help all that much.

    Anything other than an engine driven pump doesn't make sense because a sea water pump must remain in sync with engine RPM.

    Exactly my next thought.

    In the large scope of things, they could have pulled the fuel tank, had it modified to accommodate the pump, and went from there.

    One big hassle, but one time only!

    They were thinking of their bottom line. That is ... they told the client that it was no problem to pull the engine each year to replace the impeller as part of the yearly haul out. I guess they forgot to tell him what that would cost.

    I'm still trying to figure out how he can do this but I can't see how.

    Gary,

    Gary, I never thought that I'd see the day when I'd recommend a belt driven sea water pump.... but perhaps that day has come!

    What were those knuckleheads thinking of?
