    Frozen Block?

    If you look on eBay there are a few guys who part out boats and advertise windshields. Probably have to be really lucky to find what you need. if you can find out what Taylor glass number originally was on there may help as windshields can fit several boats

    Mercruiser 888

    There a couple things. A marine carb is built to with bowl vents such that if it overflows it dumps the gas down the throttle bores , also does not have a fast idle cam, jetting is likely a tad richer as marine engines run cooler due to open cooling system. The fuel and vapor control on a marine...

    Winterizing a Merc A1-G1 Block Question Antifreeze

    No only one block drain and a manifold drain. Other Side of the block has the lifter galley no drains. I had a 3.0 for 20 years, Makes it very easy to winterize. if your drain is plugged on that side get the peacock out and figure out a way to open it so it drains otherwise you will be looking...

    Frozen Block?

    These marine engines are basically truck or industrial motors. Not rocket surgery. Biggest thing you need to watch is stringer and transom rot with the age of boats you are working on save your receipts for the machine shop work on the 3.0. Yes it’s worth more than $315. If you have some back...

    Frozen Block?

    Yes unusual but not unheard of for a core plug to get pushed out and not crack the block If it was magged and pressure tested I would think it is ok. A neighbor had same issue because he waited until after first freeze to winterize. Put in a core plug in and seeemed like no water was getting...

    Mercruiser 888

    Kenny has been around the block maintenance wise. Obviously he would not be suggesting it if he didn’t think it was part of the issue. Likely the carb set up for a universal automotive application is not either sized or jetted correctly for marine loads and the altitude u are running at What...

    Mercruiser out drive compatibility

    Oh man I confused myself sorry to the OP and others if you are putting a 6 cyl drive on a 4 cyl engine then yes you need less pitch . I thought you had a 6 cyl engine and 4 cyl drive. …I’ll shut up now

    Mercruiser out drive compatibility

    Ok that’s what I was getting at , assuming the original prop hit the correct wot rpm you will need a higher pitch prop to account for the higher gear reduction in the 4 cyl drive. as an example I repowered my current boat.it originally had a 4.3 V6 with a 1.81 ratio drive. I upgraded to a 5.0...

    Mercruiser out drive compatibility

    I might be getting stupid but I thought he was not switching engines but rather drives - going from a 6 cylinder drive (1.65 or 1.81) to a 4 cyl drive (1.98) so increasing the gear reduction

    Can I use this Y pipe

    Would have the welder face the sealing surface on belt sander etc. If there is a local machine shop that can weld aluminum should be no issue but do as you like

    Bravo 1 to Bravo 3 Conversion

    yes you can but depending on the drive ratio you may need to reprop. Best bet would be to see if the 2007 was offered with a 5.7 B3 and what ratio and what props it would have come with to get a good starting point. I would suspect a smaller boat with bigger engine would have a lower...

    Can I use this Y pipe

    yeah you probably can use it with a washer to make sure it bites, could also fins a local welder to repair it. If it were mine I would weld it up and not screw around with a seal that could sink a boat

    Mercruiser out drive compatibility

    If he is going from a 6 cylinder to a 4 cylinder drive doesn't he need to increase pitch?

    Mercruiser 888

    Delta Cams and Powell machine company are two guys who regrind cams if needed. With the general trend to rollers and issues with flat tappet cam and lifter failures (due to offshore junk) not a lot of guys doing HFT but I think they could help especially if you have a good core

    Mercruiser 888

    First verify the tach is correct vs a shop tach as a sanity check. Dont care if the tach is new, easy to do rev it up in neutral see what shop tach says vs dash tach. IF you have a prop shop that will let you try before you buy that is the best way to go. I would start with a 15 based on what...

    Automotive Diagnostic Tool

    I love chit made by Germans for Germans... actually the one I got for like $100 works pretty good. I think part of the issue I had was the code was in the trans or chassis seeing an error in engine temp sensor... yeah very german... car was idling like chit. reset the code runs fine since...

    Mercruiser 888

    I know some of the older engines had really low WOT ratings but would think a ford 302 would be happier mid 4000's as well. I think some are available in 13"s like this black max, but you will definitely find less options below 15" pitch...

    Acura 3.2L Noise?

    Take the drive belt off and start the car to narrow it down to internal or external. Wonder if it is something with the variable valve timing . I’m a Toyota guy and they have issues with VVTi sprockets that make similar noises. no codes being thrown?

    Mercruiser 888

    yes Probably a 15 will do it. Certainly you wont have direct pitch drop to rpm increase if you are bouncing between 3 and 4 blades but you can figure 400 rpm change for every 2” pitch change up or down. as an example as mentioned I bought a boat in need of a repower. Originally had a 4.3 /190...
