View Full Version : Draining the gas tank?

09-15-2004, 05:24 PM
I recently purchased a 89 ProStar 190 but it has been sitting unmaintained for 2 years. It has a half of a tank of gas that I need to drain. Any suggestions?

Just for the record I have offically banned the previous owner from every owning another Mastercraft for abusing this one! :mad:

Flush the fuel line(s) when you drain the tank. You'll also have some varnish in the tank so it may be easiest to drain it, use a good fuel system cleaner(like carb cleaner in a 1-5 gallon can) and then reinstall it. You may also need to have some work on the carb, too. If you want to speed things up, get yourself a cheap electric fuel pump (volume, not pressure) and attach a couple of wires with alligator clips so you can just clip it onto the battery, with an inline fuse, of course. Then pump it into whatever gas cans you have, unless you can go to a place that services gas tanks, since they need to dispose of bad gas on a regular basis, anyway. If you have a place near you that takes in hazardous waste(like Waste Management), even better since it may be free to drop off.

Its should probably be drained.. If it was kept inside, Open the gas tank filler.. Does it smell like gas or varnish?? If varnish, drain it , change all fuel filters and be prepared to clean out your carb....

If it smells OK, dump in some stabil and some gas dry, and give it a go.. I would try to burn all the gas out that I could and put some fresh SUPER with stabil in it.. Then change your fuel filters.....

Just my opinion......

Unfortunately it smells like varnish! Should I replace the fuel lines or can I just put fresh gas in the tank (with a cleaner) and run the fuel pump into a gas can until the fresh fuel makes it to the carburator?

I guess the next big question is should I try a cleaner and hope for the best, have the carb rebuilt or buy a new one?

I plan on replacing the impeller and lubricationg the cylinders before I turn the motor over. Anything else thats a must?

John, just keep talking. I'm not going to jinx this one. You'll know I won it if you see my boat in the "marketplace soon."

09-16-2004, 03:51 PM
I haven't found any real problems with the boat. Needs a good compounding and wax, deck needs to be sanded and oiled and I bought a new impeller and blower hose today.

I good it so cheap because the owner was feeling guilty about abusing the boat! OH Yeah, he is a very close friend too.

I use to have a 1987 Prostar 190 that looked alot like your new toy. It needed cleaned up and buffed when I bought it but with a few weekends of work it looked preety good. I used it for three years then traded it in on a newer MC. When I traded it the dealer gave me $1,000 more than i had paid for it. I taken care of, these things really do hold there value.

You may not want to get that boat looking too good too soon or your friend may hvae second thoughts. Tell him how hard you are working and how much money you are sinking into that hole in the water so he feels better.

09-16-2004, 05:21 PM
that's more the price I am looking for too. :)

He has to sell it back for a $1 when the divorce is final.....

09-16-2004, 07:08 PM
ouch! that would suck :(

09-16-2004, 08:35 PM
At this moment it is only worth $1, I can't figure out how to get the darn plugs out to lubricate the cylinders before turning it over. I haven't been able to get the impeller out either.

By the way I am hemorrhaging money already!

Box wrench, I get it. I'm an idiot!

09-16-2004, 10:06 PM
Well, if you don't want it now, I'll give you 10 bucks for it. Pure profit!

09-16-2004, 10:45 PM
I like the way you think, but I think I'll pass.

09-16-2004, 10:55 PM
I'll give you $20 right now.
