    I/O (Sterndrive) Conversion to Outboards

    Quick Update . . . the Admiral wants to get an estimate of what it would cost to have a conversion of your current boat done. there are a couple boat yards in my area that do that sort of work. So, we'll see. My guess is $100K+ . . .

    Why I do not have new boats.

    I buy used boats, because I don't have enough $$$ to buy new in the range of what I want. Additionally, buying used you get to see the boat's 'weaknesses' since someone has used it for a while. Plus, you are not bothered by the warranty stuff, which boat companies never seem to honor. So, it...

    When do you pull your freshwater boat?

    @cyclops222 The link below is one 'test' of the empty tank theory, showing no water condensation. I wonder if you have links to other tests? https://marinehowto.com/does-an-empty-marine-fuel-tank-condensate/

    When do you pull your freshwater boat?

    Actually, I off load the fuel (until I get bubbles), then add back some of the fogging cocktail to do the winterization. Then what little is left stays the winter.

    When do you pull your freshwater boat?

    My boat is moored. I take it out any time between mid-September and mid-October, depending on my travel schedule, hurricanes, etc. Freezing temperatures typically are not until November. I usually off-load the fuel and use it in the vehicles.

    1997 7.4 MPI engine stalls on quick acceleration

    MPI engines would require the computer diagnostics in order to troubleshoot. Otherwise, you will be throwing parts at it. Have you checked the basics, like timing, temperature? Post the serial number of the engine, as that helps with specifics. Can you reach the spec RPM at WOT? ( which is...

    Cheap floor and foam replacement for weekend.

    Not the best of plans, and probably will not work out for you. If you want to get rid of some of the water weight and plan for the proper rebuild next year, you could try to suck the water out of the foam filled compartments as an initial step. (if they are in fact holding water) Since we...

    Water Pressure Sensor . . .

    I have not put the new sensor in yet, but in our last boat outing the old one started working again. 🤔

    New guy, floor repair questions

    @Racer223 - Hopefully the picture upload feature will be fixed soon and you can upload some photos. That way we can see what you are seeing. As mentioned, the boat is probably saturated. Post the the HIN that can be found on the upper starboard side of the transom, if you have any questions...

    Cooling orifice tube

    200 (ish) seems a bit high. Should be more in the 160-180 range. The senders and gauges are not all that accurate, so do verify with the IR thermometer

    Cooling orifice tube

    What's a cooling orifice tube? Typically the temperature is taken at the thermostat housing. You may want to get the cooling flow diagram for your engine. You can also use an IR thermometer to sample the temperature at different areas of the cooling system and compare it to the gauge. In my...

    Too big a battery harmful?

    Sounds like a made-up story. The starter will draw what it needs. The only thing with 2 batteries is that the voltage drop while cranking will probably be less than with just the one, which can be a good thing. Many boat electrical system are set-up with just that . . . a way to use more than...

    Overheat after high RPM run 350 MPI from 2001 with bravo one

    It sounds like you have an open cooling system (i.e. raw water cooling). One thing that can happen with this type of system is that the water running through the engine can/will come to a boil if the engine gets too hot and cause the temperature fluctuations that you mentioned. As mentioned...

    I/O (Sterndrive) Conversion to Outboards

    I joined up an OB conversion group on FB the other day. Not many members (300 ish), and it looks like the sweet spot for doing OB conversions is older boats, traditional transoms, and low tech controls. Also added a boat (Sailfish) to my list of prospects. CY 338 OB - Wicked pricey -...

    LiFePO Batteries ???

    Quick Update. . . I ran into some engine issues today while waiting for dock space to open up to pick up the crew. The stbd engine started throwing fits the alarm went off, then it died. I got it started, but I wanted to check it out once we got to our anchoring spot for the day. No codes...

    Boat age vs financing.

    My brother recently took a new job selling used (lightly used) boats. He told me that a lot of people finance their boats. I've never been 'allowed' to do that. :LOL: Of course there are some options (personal loan, home equity, etc) if the boat itself is not 'eligible' for financing.

    O2 Sensor codes . . .

    Thanks everyone for the help on this. Looks like I'll be buying the special socket and swapping left & right to see if the problem moves with the sensor.

    O2 Sensor codes . . .

    Thanks @muc . . . Looks like I got to get one of those O2 sensor sockets to do the swapping. In my engine voltage efforts, I did have an issue or 2 where one of the 10amp fuses got knocked loose. I'll have to check those again.
