    Standard prop on Merc 2000 9.9 4 stroke?

    (Hmm... tried to post but didn't seem to go. Apologies if this gets posted 2x) I have a 2000 9.9hp 4 stroke long shaft merc on a 14' Starcraft. The Starcraft has a floor, casting deck, trolling motor, and a hefty 12V battery. With just me in the back, it runs 9.2mph and never gets on plane...

    Any idea what jet size is for sea level 9.9 4 stroke?

    I'm in the process of buying a 2000 Merc 9.9 4 stroke, which has been in Colorado its whole life. It is now headed to about 1200' of elevation. Owner does not know if this carb has been re-jetted for altitude. It needs a bit of carb work, as the float either sticks or is leaking. I'll be in...

    2011 DF115 Ugh. Intermittent PTT problems

    My PTT is being a PITA :-) Once in awhile, the engine fails to respond to a switch call for the PTT to raise the engine. It will lower, but not raise. No hydraulic motor running for a raise command. It will not respond to either the throttle PTT Up button, nor will it work with the engine...

    I/O vs. Outboard HP rating

    OK, I bet this has been beat to death, but I searched and could not find it. How does I/O rated horsepower compare to outboard rated horsepower? Is it rated at the flywheel or prop? The I/O has two direction changes, the outboard only one. Thanks in advance.....

    Do soft spots on decks stabilize if kept dry, or do they continue to spread?

    Still in the hunt for a boat, and found a clean one with good mechanicals, 98 Monterey Montura. Only thing I can ding it for is a soft spot in the deck which is off to the side of the boat. The soft spot feels to be about 3"-4" in diameter. Do these sort of things stabilize if kept dry, or...

    Crazing on hull and paint flaking off outdrive.... should I run?

    Looking at a boat to purchase that is fairly clean. Owner has had it 10 years or so, claims it has been stored in garage most of its life and moved outside this past year and kept well covered. Most of the boat (upholstery, carpeting, most of the hull) seem to support this, as the boat is very...

    Negotiating for a boat....

    I'm boat shopping. As part of this process, I will be enlisting the aid of a shop to do a professional survey. My target boat is 18' to 20' runabout, I/O open bow for fish and ski activities. Probably 4.3L to 5.0L. I'm guessing in the $7500 to $10k range. I posted another thread on a...

    Help me build a check list for purchasing a used boat.....

    There has to be threads on here on what to look for when buying used. I did a search and came up empty. I'm trying to put together a list that would be used to narrow the field. Prior to taking it on a test run or taking it to a shop for a pro survey. Target boat in this instance would be...

    Why are so many used boats "rebuilt"?

    I like to browse craigslist I/O oats. So many of these boats look to be well maintained (very clean upholstery, clean hulls, appear to be stored inside, etc) are advertised as "just rebuilt" or some such advertising. I have multiple 10+yr old cars, and the engines in those are just fine...

    Need help thinking about my "next" boat

    Was out fishing with my daughter this past weekend in our 17' Sportsman aluminum fish /ski. We typically rig it with two downriggers and two top lines out the sides. With tackle box, cooler, anchors, rope, and miscellaneous stuff, we are cramped. Hard to get around at all. We had a double...

    A truly weird boat start problem

    Boat has not been started since spring fishing season. Had some issues with it, did a link and sync, and parked it. Going fishing for the first fall trip tomorrow. Knowing that I was going to have to fight with this a bit, I carved out the whole afternoon to get the motor running. Put in...

    Where is cooler drain for Sportsman Bluefin?

    Hmmmm. I loaded up the port side bow cooler on my 1988 17' Sportsman Bluefin. Noticed that there was a drain in the bottom, but for the life of me I can't tell where it drains to. Does this just drain into the hull and is subsequently drained out the stern plug? Yuck if so.

    How to fix engine splash from transducer? (see pix)

    I'm having some problems with a spout of water rising up and hitting the side of my motor at speed. I suspect that it is because of my fish finder transducer. But I can't tell if it is hitting the nose of the transducer and deflecting up, or if it is pushing up through the mounting bracket...

    How to adjust throttle cable engagement?

    1988 85HP Force.... Took boat out for first run since all this carb cleaning / synchronization business. Ran great once warm. Best ever. Still a bit of an issue though with the range of adjustment for the throttle. Would not start cold, and had to remove the ball joint linkage in order to...

    Eureka! But now I need help finding a part number and source for this carb part...

    1988 85hp Force Was going to take my boat out for a test run tomorrow, and tried to do a cold start here at my house. No joy. Found out that my idle advance was too much, and the engine was not choking right (probably flooding from the primary being open). Pulled off the cam linkage, let...

    Why has there not been more of a move to fuel injection sooner?

    I've been surprised by a few things about boats.... 1) Why the heck they don't have air filters. How much more could that possible cost? 2) I'm amazed that there are not more fuel injected motors through the 90's early 2000's. I've been shopping used boats... late 90's, early 2000...

    Next.... timing questions....

    Force 1988 85hp. Questions as I prepare to check timing. 1) I see some timing marks on the flywheel, but they are not marked. I have a single mark on the flywheel, and then (if I am remembering right) if I progress clockwise along the flywheel, I come to three other marks, each about 1/8" or...

    link and sync... operation of carb butterfly

    (edited initial questions) Working on link and sync of carbs. Initially confused about butterfly operation, but I think I have that resolved. Was unable to adjust roller to contact cam. I have two means for adjusting idle. One is to just lengthen the ball linkage. The other is to...

    Clarification question about the synchronization sticky....

    For step 8... the instructions say to turn the needles 1/8 at a time. Question : Does this mean turn needles on all carbs by the same amount as I proceed? Not just one carb at a time to see where the engine starts to sag or sputter, right? I'm guessing that I adjust all carbs by the same...

    Debugging tach for a force now.... can you please check this electrical thread?

    Asking Force gurus to specifically take a look at this tach thread. Good news was that my carb cleaning resulted in a motor that starts. Bad news was that I installed my tach late in the evening and may have screwed it up. Please take a look...
