    Deck plate question?

    If it's only used to check the gas tank I would put some silicon just above the rubber O ring , just enough so it does not ooze out. The only time I check out that deck plate is if I have a issue with the sending unit or gas gauge.

    Carburetor choke not opening?

    Whatever the opening size was I used a drill bit of that number for the gap measurement to get the correct opening. So if it was 1/8 I grabbed that bit ,held it in the opening and adjusted the choke plate so it stopped there.

    Carburetor choke not opening?

    Not sure about the 3.0s but my 5.0 with a Rochester 4 barrel the manual calls for the choke plate to have a gap of 1/8 to 5/32 when cold. Can't remember the exact number but it did call for it to not be completely closed.

    1979 searay 300 trips breaker no shore power

    Do you have a circuit breaker on your control panel ? Other than that all you can do is trace your AC power to see if you burnt anything up. Usually one of the two breakers I mentioned will trip before it gets to something shorting out.

    1979 searay 300 trips breaker no shore power

    Ok. so have you reset the breaker with the shore power cord not plugged into the boat. Then plug it into the boat after you have all your AC switches turned off. Then turn on a few low draw switches and check for power .

    Mercruiser 5.0 TKS vs 4.3 MPI

    Boy it's not the same hull. It does not have the same torque. It is not worth more. It will wear out quicker. The fuel milage difference isn't even worth discussing. Yes after sitting a week or so the MPI will fire up sooner than the carb. After the 5.0 is started one time it will fire up as...

    Mercruiser 5.0 TKS vs 4.3 MPI

    The big difference in your fuel consumption numbers are probably bc of a few things unless they were in the exact same hull ,which I doubt. The 3.0 was probably in a smaller ,lighter hull than the 5.0 . The difference in drag and weight would make a huge difference. There is a formula that is...

    Mercruiser 5.0 TKS vs 4.3 MPI

    The " fuel economy " is based on how heavy your throttle hand is. The - gas - difference between the 4.3 and 5.0 is minuscule. The 5.0 has more torque which means its going to get up on plane with less gas than the 4.3. Has more cylinders which means less wear and tear on the engine if your...

    258 Vista. I think I want one

    What particular boat are you referring to ? If you are referencing my boat about your trailer comment you may want to read it again. I responded about boats in " the 30' class " not the boat that he originally was asking about.

    Owners manuals

    Maybe the mods could post a sticky at the top with that heading . Then explain to the people that are too lazy to use the search engine on here to figure out they are non existent with the exception of a few brands.. I know of two ,Boston Whaler and Rampage and that was from the late 80's and...

    5.0 labeled on air housing ?

    Buddy looking at a 2006 boat and he sent me a picture of the engine. The air cleaner housing has specs listed and it shows 5.0 [ 350cid ] written just like that with parentheses as shown. Along with a big 5.0 in the center. A 350 is a 5.7 so what gives with Mercruiser showing it as possibly a...
