    Inboard Engine question

    A Mercruiser 470 . . . :unsure: You'll get some comments on the engine itself. 3 things . . . Fuel Spark Compression You'll want to figure out which of those 3 you don't have. Spark is fairly easy to test, and compression is not so bad either. If you have those 2, then fuel may be the...

    Preloading without the rolling dial torque wrench

    The rolling torque wrenches have gotten a bit pricey, but loosing a top-end gear set isn't exactly cheap either. Years ago, I bought the Seekonk Rolling torque wrench . . . I recently found it when I was cleaning the garage. :LOL: Get the proper torque wrench or have a reputable shop do it.

    Chaparral Mercruiser Prop Question

    Which Chappy SSI model? The 21 (3100 lbs) or the 23 (3600 lbs) The original prop (14 x 19 Al) seems to be optimized for the top range . . . maximum speed. It is surprising that the 17 pitch 4-blade had such a dramatic effect. . . . but you did not state what the RPM was with the 19 pitch...

    Possible buy (engine option)?

    BTW - There is plenty of wood in those boats. @lukecono . . . 1986-1987 was a transition year in several regards for Formula. 1) They were transitioning their designs towards the 2-piece 'clamshell' construction. By 1989, the boat had settled into the full 2-piece design 2) They were...

    Possible buy (engine option)?

    Most of the 242LS models came with the 454 MAG (365 HP) and Bravo 1, starting in 1988. The 1987 models had the Alpha drive, which was only a good match for the 350 cu in engines. The boat is wood - transom, stringers, bulkheads and floor coring.

    Quit My Job . . .

    Yes, that VesselView and SmartCraft stuff. My current goal in life is to figure out how to get the GPS feed to the speedometer. One of my boating buddies with a Cruisers 328 has V-P 6.2's and they are no better. At one point the 'smart' system could not 'find' one of the engines and he had to...

    Quit My Job . . .

    Yup, I hear ya . . . Nothing full time, but the latest IT gig may be a few days a week. At least I'll have some extra cash to restore the O'Day Mariner that has been sitting in my back yard for the past 6+ years.

    Quit My Job . . .

    Quick Update . . . The I.T. front has been more active than the Boat Upholstery front. I got my '2nd in command' at the previous place the IT Director job where I am currently consulting. I am going to be starting a new IT consulting gig at another company that should be keeping me busy for...

    Owners Manual

    Boat manuals are usually not a thing until recently. Boats came with very little useful documentation. So, if nothing comes up on a Google search, than what you are looking for may not ever existed. The engine manual(s) may be the most useful.

    99 Monterey 276 Transom Replacement

    Also, if you have access to an infrared camera, those are effective in identifying wet/rotted areas within a hull. Another thing that you can do is use a fairly inexpensive probe type moisture meter and just drill slightly through the fiberglass coating rather than deeper into the transom, so...

    99 Monterey 276 Transom Replacement

    Probably a 1/4" drill from the inside near the leaking area and a few places higher. Go about 1" deep (the transom is 2" thick). Take pictures and save samples of the shavings, noting if the are wet, dark, mushy, etc.

    1987 Cruisers, inc - Roque 287S

    Greetings and welcome to iBoats . . . Owner's Manuals for boat were not really a thing until lately. Mostly stuff about navigation rules. There is a fairly active Owner's group on FB and you could reach out to Cruisers Customer Service for guidance. I do see that there is a 90-page manual...

    99 Monterey 276 Transom Replacement

    It could be just an assumption, so it needs to be verified before putting money and effort into it. it might be good to get the boat out of the water and take some core samples of the transom, both near the leak and elsewhere

    What would cause staining under sunpad?

    Sort of looks like mold. Who says that boat manufacturers use Marine Grade plywood ??? :unsure: :LOL:

    A couple basic testing questions

    It is hard to compare with the compression tests of others, because the methods of others and their 'pulling strength' varies, as well as the accuracy of the gauges. Therefore, if you are using reasonable methods of static compression testing take the highest value and call it good.

    A couple basic testing questions

    what do you get if you spin the flywheel with the drill on high range? You do need a few compression cycles to fully pressurize the test gauge & hose. So, you could go with the 70# number. It is just a matter of consistency.

    2002 Glastron 175sx milky oil

    It would be nice to see the oil that you took out of the engine. After you run the boat, it would be good to remove the spark plugs to see if you are getting any water in the cylinders. The battery may be bad, so see about getting a new battery.

    Towing a Chaparral 23 H2o Sport boat with a 4Runner that has a 5,000 pound tow rating

    As stated, you will probably be in the 5,500 - 6,000 range for your actual towing weight. I've towed over the weight rating, but don't tell anybody. :LOL: That tow rating seems pretty low for a 4Runner . . . 7K of towing capability would be better.

    Water Pump connections

    Those are the Whale Quick Connect fittings . . . https://www.whalepumps.com/rv/plumbing.aspx They use the water (liquid) pressure to hold them tight . . . provided that they are inserted into the fitting properly.

    99 Monterey 276 Transom Replacement

    Bummer . . . oh and welcome to iBoats. We are here to help. Many of us us fixed transom and structural rot ourselves, because we are not made of $$$$$. Anyway, $20 K is a bit pricey, but figure $2K just to take the engines out and $2K to put them back in. Usually the rot goes further than...
