    NEED Stern LIFT Prop Suggestions

    Hello Took my 2008 tuffy 1890 deepV out for a pin on the river out here. Tempest plus 27p, Suzuki DF200, 5600rpm, 12% slip. Motor mounted on the centermost hole. With a few people in the boat, it got up on plane fairly well with the trim full in. At slow speed it was fine, not blowing out or...

    Properly Fogging a Suzuki df250

    Factory service manual and owners manual do not mention anything about fogging. Seems like the engineers couldn't care less about fogging. Also, get yourself a factory manual if you intend on doing lots of diy work wink wink.

    Properly Fogging a Suzuki df250

    If you don't want to spray the intake, that is fine, and pretty pointless as I have said above. Personally I prefer to spray into the cylinders. I have not seen anyone run the fogging fluid through the fuel system in a zuke. I do see the mix method of fogging prevent intake valve rust. I am not...

    For discussion, mercruiser v6 , rochester, edelbrock

    Well... Yes, there is a possibility of fuel pump pressure jumping up. The average pressure doesn't jump up, it something else. There is a little diaphragm in the fuel pump, downstream from the main pumping diaphragm. This little diaphragm has the fuel on one side, and a sealed air pocket that...

    Properly Fogging a Suzuki df250

    I have a DF200 (v6) similar engine as yours, yours has the vvt. All the sensors are in the top of the silver intake air collector, between the two throttle bodies. So unless you fog it through the iac, (big no no) there really aren't any sensors from there on. Having that said, the design of the...

    Building a '93 Caravelle 1750 Classic Bowrider

    Couldn't help but comment on this. partly from the carb, but also a thing you might be familiar with as an engineer - diffusion. Fun fact - the gas smell at a gas station is the diffusion of gas molecules through the hose. So you will get some gas vapours while fuelling when the gas is going...

    Trailer wiring fries fuse

    Probably a common thing, but for some reason I couldn't find anything on the internet or forum about this. After pulling my boat out of the water and after that connecting the trailer lights, the running lights work for maybe 10 seconds and then the fuse blows. Before launching the running...

    Need to do some adjustments on my tinny, 115 optimax

    Hello Got a couple of questions. My boat is a 2010 lund 1725 explorer ss with a 2008 optimax 115. First, I think I am overpropped. WOT rpm spec is 5000 - 5750 rpm on that motor. My current prop is a michigan wheel aluminum 13x21 and at WOT and light load I get 75 km/h at 5200 rpm. Little too...

    Fairing a big dent in the curved part near the bow - need help/advice

    Hello Finally got around to fixing the dents in my Tuffy. The one farther back was easy because it's not curved there lol. The area where it curves I am not sure how to fair it! What I mean is, I can put the repair putty on, but how do I sand it level? It's a curved area so using a flat sander...

    What kind of prop should I use on a deep v with 200hp Suzuki?

    Hello Finally got the engine back on the boat but since the engine fell on the prop, I went to the repair shop and they gave me a sky high price. The dude at the repair shop honestly said that it is time to find another prop. So I went to the merc prop finder and it didn't give me any results...

    Suzuki df200 sat for a LONG time. what do I do before cranking it up?

    Hello I am about to crank up my 2008 DF200 after it's been sitting for a year or so on it's side (the port side). Anything I should do before cranking it up? I cleaned out the intake screen, and changed the oil and filter. I know for a mercruiser you should first prime the oil system (as per...

    Mercruiser 3.0 Cutting out at any rpm

    Hello. Recently I figured out the thumping noise in my engine, but that did not fix it from stalling. At first I thought it did, it ran good on the trailer so I decided to take it out for a spin. In the water it smelled like gas and wouldn't fire so I thought it was flooded, and rightfully so...

    What goes with a lowrance LGC 3000?

    Hello Just bought a boat that doesn't have any fish finders but it does have the black thingy at the bottom of the transom as well as a gps receiver that says lowrance lgc3000. What fish finder will work with it? I think it would be logical to get one that would work with it. It is the one that...

Before going out I pulled the drive and checked the alignment, bellows, gimbal bearing, splines and u joints. all looked in spec and when I put the drive on it popped right in with one hand. I...

    Yes, i did it..:stupid:. I was testing my trim system on the workbench in the basement and forgot it was down... Opened the cap, there was always a slight hiss noise so it didn't seem unusual this time, except that I was greeted in the face by a nice gush of trim fluid... sweater still smells...
