Hi all, Looking for some advice from someone who may have encountered the same problem. My fuel tank is leaking, likely from the bottom, it is a 20 year old aluminum tank. The main problem is how to access the fuel tank without removing the engine and ripping everything out...I have a 1997 signature 270 in excellent condition with a 7.4L mercruiser with a 70+ gallon tank I believe. There is small amounts of fuel leaking into bilge and it doesn't seem to be coming from the top of the tank, or the engine itself. I saw some posts and wanted to find out how one would access the old fuel tank? It looks like you could cut a hole and go through the floor of the aft sleeping quarters? There is no easy way to get at the old tank unless you rip the boat apart. I am also curious if anyone thinks the manufacturer has a suggested solution. Do you think chaparral would know what to do about this? I would guess it's pretty common because it's such an obvious flaw. I don't want to get rid of my beautiful cruiser because of such a simple problem but I am stuck.
So, my boat is running pretty well, but my carb has been giving me some issues. First, I have trouble restarting my engine after fueling up (so after warming up for 10 minutes). It always starts when cold, but sometimes when warm I have troubles getting it restarted (takes 5 minutes sometimes) after stopping. Next, I have a few drips of fuel leaking from either the throttle plate, or base plate of the carb, which I think shows that I have a vacuum leak. Moreover, when I run over 4,000 rpms for any time, the engine bogs. Under that rpm range I have zero issues with bogging, stalling, etc. So, I think the little area that is letting fuel out is letting excess air in. If you've followed my thread, you know I had my carb rebuilt, but upon re-installation I think I may have used the wrong base gasket. Like an idiot, I threw my old one away so I am at a loss as to which base gasket to buy. Here is my intake: And here are my choices for gaskets, can someone help me choose one for my intake please lol: http://www.ebay.com/sch/i.html?_odkw=quadrajet+replacement+kit&_from=R40|R40&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR0.TRC0.H0.Xquadrajet+base+gasket&_nkw=quadrajet+base+gasket&_sacat=0 I also want to dial in my mixture screws and idle. Any tips for adjusting these are appreciated!
