    4.3 Mercruiser cold start issues

    'nuff said in the picture below the great thing about the factory wiring. there is a feed line from the crank circuit. when you crank the engine, the bearings and cam get some oil and the carb gets fuel.

    Considering a 1995 horizon 220

    not only are parts not available for the motor, the drive is also difficult to get parts for. basically OMC has been out of business for a really really really long time. back in 1995, Four Winns was an OMC brand. They not only used a lot of OMC motors, they were owned by OMC. the quality of...

    The art of Alpha One Gen One Maintenance

    clymer manuals make great knee pads, are only OK for use as emergency toilet paper, however really suck as a manual. in addition to your factory mercruiser manual, there are videos and links in the stickies.

    5.7 mercruiser heads question.

    no such thing as a freeze plug. there are core plugs to get casting core sand out at the factory. to marinize a block, you need marine head gaskets, marine cam, the forementioned brass or stainless core plugs and a marine circulating block.

    2004 volvo penta 5.0 gl-e camshaft

    agreed that the area of the block just inside the fire ring has rust. however not sure why. remember, the SBC bolts used since the late 80's are a one-time-use torque-to-yield bolt. you will need to get new head bolts ($35 for GM, about $130 for ARP)

    Need the Prop Gurus!

    agreed, post your compression numbers. is hole #3 low? 4600 RPM is way to low of an RPM with the 17p prop have you weighted the boat

    2MPG boat for cruising the ICW ??

    I would suggest you actually plot your fuel use. You will find your average consumption higher than you think. Plan on 6-8 gph average and rejoice when you get more. Too many no wake zones and traffic in the ICW to simply cuise along just above idle

    Drain Plug Rot

    Fiberglass boats are designed to last 15 years. Anything past that is a bonus. Since the 2022's are now being built, your boat is 32 years old and your transom is soft, guaranteed you find other issues. I would plan on a full hull restoration

    handheld vs fixed mount VHF

    I have a hand held that now is used for the ditch bag. The problem I had in the north woods was I was the only one around for miles with a VHF until the warden came by. Most boaters only had cell phones. YMMV

    2MPG boat for cruising the ICW ??

    If you want fuel economy in a boat, get one with sails or oars. Too many factors effect fuel economy including load, bottom condition, wind, current, temperature, load, hull design, etc. At a minimum you are looking at diesels which have a BSFC of 0.33 vs a spark ignited motor with a BSFC of 0.4

    Motor swaps

    Block, heads and crank do not know if they are in a boat, a truck, a car, a genset or a forklift. However the whole longblock does. Cam, gaskets, core plugs, accessories, electrics and industion are marine specific Dont even think of bolting the motor in the boat until you change the core...
