    Getting a 2024 Merc 150 4 stroke- any surprises?

    For what it's worth, I know a few people who have bought the 115hp-150hp merc 4strokes in the last 10 years and not had any issues with them. These are not high hour users. Just seasonal.

    What do these 2 rubber hoses go to?

    Gap should be .012" - .016" How did you check for spark? If you used some sort of spark tester that probably won't work. You have to make sure the plug is well grounded and check for spark across the electrodes in a dark place. If you have a multimeter you can test the condensor. This test...

    It also could be the neutral safety switch or the stop button that's causing trouble.

    What do these 2 rubber hoses go to?

    Did you take the top cover off the grey pulley (if possible) to see if there's points under it?

    1978 Starcraft I/O Super Sport 18ft Prop Size Question

    Are you sure the drive is able to trim in all the way towards the transom? Also, your prop, speed and rpm numbers seem odd. With a 15" pitch prop you should be over revving by a lot at WOT. A 14.25" x 21 or a 14.5" x 19 should work well for that boat.

    It's possible that if it had points there might be a window on top of the grey pulley to access them. But maybe not.

    What do these 2 rubber hoses go to?

    The CDI coil looks like that. I don't know what the points version would look like. If there are points they would be under the grey pulley. Check for spark in dark place first. Both plugs fire at the same time.

    What do these 2 rubber hoses go to?

    Spark on these motors is very hard to see. I usually turn all the lights out in the garage or put a cover of some sort over the motor when testing for spark. Is the ignition a points type or CDI? If points, you might want to clean them. I believe they're under a cover on the small pulley.

    I got got on a new purchase

    That could just be the result of condensation. Have you tried to run it to see if water leaks anywhere or the oil gets contaminated?

    That would make sense.

    What do these 2 rubber hoses go to?

    Those holes are open to the elements so you should be ok. If you run it in a tub make sure it's about 18" submerged. I won't be running mine for quite awhile but now I'm curious and will check it out. Let us know what happens! Update, I found a video of mine running in a tub and it shows the...

    I don't know. Maybe an exhaust bypass?

    What do these 2 rubber hoses go to?

    Those were added on by someone. Normally there's two 1/4" holes there. Looks like they've been tapped for those brass fittings.

    Dock question: how do these sections hook together?

    I thought it was a floating dock as well.

    Dock question: how do these sections hook together?

    The decking should come off in sections giving you access. There should be a corresponding hole in the hooks that don't show in the picture.

    OMC or Yamaha

    Neither is the answer but if for some strange reason you had to pick one then OMC.

    Boat to store inside garage ?

    You won't get a 19 foot boat and trailer into a 19 foot garage I don't think.

    Replacing lift cyl power trim hose,how much heat to use?

    A name brand wrench would be best but there will always be a bit of play. If you have room you could use a pair of vice grips to close the wrench to reduce play. Like Scott06 said, if it's the line why not cut it and use a box end wrench?
