    Vibration/Shutter at low RPM's on a Suzuki 225 w/ Cracked Lower Unit

    I have read the reasoning behind the crack (corrosion building up between the propshaft carrier nut and threads) and I am going to get mine fixed but I had a few questions 1st. My crack is quite substantial but it hasn't made it up to the gear case yet. The fluid is perfectly blue with no...

    Just bought a boat with 2001 or 2003 Suzuki DT225... What to look for???

    Engine plate shows DT225 22501 - 371273 While on test drive in gear below 3000 rpm you can feel a sputter though out the boat. However if you give it more throttle it revs up nicely and runs smooth. The highest rpm we went was 4200 rpm but I wasn't driving and I wasn't asking him to push...

    I am going to look at the above boat tomorrow but it does not have a motor attached. I am fine with that and have repowered a hull before so I know what I am getting into.

    Can the timing belt squeak on Merc 1500?

    On our last trip I noticed a squeaking noise (very similar to a squealing belt on a car) that wasn't a constant squeal but kind of like chirping/squealing. Sorry for the bad description. The noise didn't happen until we were already at our destination so no choose but to try and get back home...

    Water Pump Flushing Attachment Merc 1500

    My 1974 1500 has a flushing port on the water pump that is 5/8" x 11 thread, but i can't find an attachment that will work with that thread. Does anyone know where I can find something like that that can be adapted to a garden hose thread?

    95% water 5% gear oil in lower unit Merc 1500

    As I move along with this motor I am slowly starting to replace everything now that it runs good, cools good, and is pretty much water ready. Today I went to replace the gear oil and I think I am being generous when I say 5% gear oil. I have already replaced the water pump but I did not buy the...

    Now that I slowly getting the kinks worked out of my motor I am trying to make my boat a more enjoyable environment for my buddies. Currently you have to yell to one another if you at anything over idle. Seriously YELL if it is over 3000 rpm. I also have two seats in the back of the boat that...

    Crazy Idea...1974 Mercury 1500 Manual Fuel Sprayer for cold starting

    My tower of power, like everyone else's I have been told, is VERY hard to start when it is cold. I always have to turn it over for ever before it tries to fire. However if you use starting fluid it will fire right up. I do not have the original controls on my motor so i don't have the high...

    Using Large Hub Prop on Small Hub Lower Unit...Pros/Cons

    I have a 1974 Mercury 1500 Inline 6 and it has a 4" diameter housing on the lower unit. The original 13.25 x 19 4-blade prop has too much pitch for my heavy 20' Proline center console (3000 lbs when full of fuel and loaded with friends) and it will not get on plane very easily. I have been...
