    270 leg water pickup

    without pictures, none. is there a bottom pickup on the hull? I would grab the factory service manual for your drive and decipher what is what. if you ran the boat for more than a few seconds with a dry impeller, your impeller is now toast.

    Merc 7.4l 454 Gen 4 to 5 interchangeable?

    to get that on a dyno is one thing. however you have to add lots of duration with lots of overlap to the cam....... all top end power, no lower RPM power and it would suck water up your exhaust and hydrolock your motor in a boat once you tried starting it. again, you have to understand...

    broke driveshaft

    fatigue cracks can start if you have a dead cylinder and run the motor for a while. the un-ballanced loading is not as bad as cyclical reverse loading.

    Trimming with Outdrives and Trim Tabs

    trim your drives up/down as needed. trim the tabs both down just a touch to bring the bow down if you need, however as Ted stated, mostly for port to starboard list. maybe read the trim tab owners manual. https://bennetttrimtabs.com/wp-content/uploads/2015/02/owners_manual.pdf

    Merc 7.4l 454 Gen 4 to 5 interchangeable?

    You cant take a 330hp boat V8 and get 560hp without a supercharger unless you change crank, cam, pistons, heads and intake. You need to do some reading on cam overlap and reversion You can take a 330hp gen 6 motor (oval port heads with 360-370hp at the crank), change cam, modify the carb and...

    Merc 7.4l 454 Gen 4 to 5 interchangeable?

    You need to build a motor for HP. There is a limit to what you can "bolt on"

    broke driveshaft

    you have to remove the drive, then the motor. if you have a jack shaft, you may be able to get the shaft and flywheel housing off, however do not count on it. Welcome aboard.

    Just thought I'd share a nice photo.

    This is a picture of the light-house in my home-town of Manitowoc Wisconsin. the photographer (Anne Barbeau) is a pure natural, untrained lady with a great eye (photography friends are jealous). the view is from the area near the YMCA, just down from the USS Cobia, about 2 blocks from where I...

    Performance question

    being a 1988, I guarantee your heavier than you are supposed to be. check for moisture. a better ratio drive is not a bad thing, it would allow your motor to spin up higher get rid of the automotive distributor only getting 4300 is either you are over-propped (probably not the case), or...

    Merc 7.4l 454 Gen 4 to 5 interchangeable?

    yes. as a side note, your 1997 boat should have had a gen 6 motor in it to begin with.

    Merc 7.4l 454 Gen 4 to 5 interchangeable?

    then you didnt look in the right location. https://www.mortec.com/location.htm however the 14015445 is the casting number, making it a late Mk IV block i would skip the Gen V and go straight to the Gen VI myself.

    Volvo DP leak.....HELP

    white caulk is a giveaway that something is wrong. there is a transom seal that if intact, does its job well. usually caulk is done as a bandaid. how long have you owned the boat?
