    6 gallon gas tank no vent??

    Recently bought a 13' skiff (30 hp Evinrude) and the 6 gallon tank it came with doesn't seem to be venting. After a couple of days of sitting I go out and the tank is noticeably full of positive pressure and when I release the cap it releases it. I thought these little 6 gallon tanks were...

    '98 Evinrude 30hp losing WOT RPM when hot

    The above engine will run 5400 WOT when I first get out on the bay and it's not very hot. After running a while at cruising speed, around 4200 RPM, when I open it up again it will just barely make it to 5,000 RPM. I've noticed that it's done this the last couple times out, which are the only...

    1998 Evinrude 30hp

    I just bought a small boat with this engine on it. I've never had an engine this small and was wondering if there is supposed to be a small air box or something on the front of the carb? Right now the carb is just open in front. There are some threaded holes on the front of it like something...

    OMC/BRP Cables vs.Teleflex

    Snapped a throttle cable over the weekend and am just gonna replace all 4 (twin Evinrudes). Pulled one out and they appear to be original OMC cables from 1996. I was gonna go with OMC/BRP again since these lasted 17 years, but have been hearing/reading a lot about the Teleflex Extreme cables...

    Navman Trackfish 6600

    Any opinions on this unit, or Navman stuff in general? I know they aren't made anymore and were basically the same thing as Northstar. I can get the full unit with GPS antenna and transducer for $600. I was looking at the Garmin 740s and almost pulled the trigger, but then I came across this...

    Evinrude DI's - best fuel additives to use?

    Yami guys swear by ring free, Merc guys by Quickleen. I just got a pair of Evinrude DI's and want to hear what other guys are using in them. Is the Carbon Guard the best thing to use? Is 2+4 just for storage? I always use Star Tron in my fuel to keep it fresh and to treat the Ethanol. Should...

    '04 200hp Evinrude DI RPM "bouncing" at cold start

    I have a pair of '04 Evinrude DI 200's. The starboard one will start right up cold but the RPM "bounces" up and down a bit for a few seconds, not a rough idle just kind of goes up and down, for maybe like 20-30 seconds then it evens out and purrs, giving it a slight bit of throttle helps it as...

    3 batteries with twin engines

    Re: 3 batteries with twin engines Ok Don I pulled the switches off last night and traced everything out and put it all into your diagram. Let me know what you think. It looks to me like I should be running each engine switch on #1 and the House switch on #2 to draw off of the House Batt, but...

    3 batteries with twin engines

    I just got a new boat with twin outboards on it and there are 3 batteries. A Port, Starboard and a House, all 3 on their own switches. The PO was running all 3 batts in the ALL position on each switch. I just wanted to make sure this was correct or if I should be running them in different...

    87 Octane in a EFI Merc?

    Can I use 87 octane gas in a '99 Merc 250 EFI? I was told to run at least 89 but that 93 was preferable, and that 93 runs a bit cooler. I've been using 89 but wanted to see if I could just start using the 87 from the corner gas station, as it's like .70 cheaper per gallon. Is there a higher...

    Would you keep these batteries?

    I took both of my batteries up to Advance Auto to get load tested because my multi-meter was showing them sitting at 12.0 and 12.1 while the analog meter on my load tester was showing them sitting at 13.0 and 13.1 and they are load testing fine on that gauge too, so there was a full volt...

    Can older batteries hurt an alternator?

    I can't get my batteries to take a full charge. They are still strong and sit around 12.6v and load test fine, but my charger can never get them to full charge to where it shuts off and they get real hot when charged for a while. They are Group 24 1100MCA EFI rated batteries. I've noticed my...

    Where else can I find my serial # without a transom mount tag?

    Basically the title is my whole question. I have a '99 Merc 250 EFI, the transom mount little tag is missing and I need the serial # for some parts I need. I thought maybe the freeze plugs but that # looks like it's a bunch of zero's all in a row, assuming that's not the serial #. Maybe on...
