    MerCruiser 5.0 MPI diagnostic connector

    My main concern would be the fuel smell in the engine compartment. That is how majority of boat fires / explosions start. Can't blame a flooded carb, since it is MPI.

    Last update. Bled brake system using a mighty vac pneumatic operated pump out and a brake bleeder tank that keeps MC fluid tank full while bleeding. Took all of about 45 minutes and about a quart of brake fluid to completely flush out system with new fluid with no assistance. Works far better...

    Diagnosing trim gauge issues

    Trim indicator in full up all the time indicates an open circuit (bad sender or broken/disconnected wire somewhere) or a bad gauge. On back of gauge, with power applied, short the "S" terminal to ground. If it goes full down, the gauge is good and your problem is in the wiring or sender on...

    can someone let me know what fuse sizes?

    I do applaud your incentive and effort to upgrade / improve the deficient existing electrical system, but taken a step further to ensure reliability and safety may have been warranted. Neat and tidy would have been a goal for most, but isn't considered in this. Just suggesting that some insight...

    You should find one of the templates and use it to lay out the cut out Mercruiser does offer a cut out jig, but it is pricey. Maybe find one used??? Here is one on e-bay. for 80 bux...

    can someone let me know what fuse sizes?

    Personally, I would do some reading up and watching videos of proper marine / boat wiring techniques and best practices.

    NMEA adapter to connect Garmin chart plotter and iCom radio?

    Here is the connections DWG I used to connect my Std Horizons DSC to the new Garmin Echomap 74 SV I installed. Works fine. As others state the NEMA 0183 connection is bundled in the power cord

    Did read the voltage at the EoH (black power feed wire on the terminal connection box right next to EoH) and it was same as battery voltage (13.9 VDC) on truck, +/- 0.1 volts) with EoH running at full input signal. Connected the Fluke, reading max / min to the black and ground. Also checked...

    As stated, I did. Multiple tests with different outputs on P3 brake controller confirm P3 brake controller output is same as input to the EoH unit, from min setting to max, with EoH unit running..

    Converting to Electric over Hydraulic this week

    Mine is an older '04 4x4 Lariat. The red, white, black and blue wires are all 10 gauge. The trailer battery charge relay is backed up by a 30 amp fuse. When engaged, I can hear the EoH operate from the cab with back window open. Connected my Fluke up to the EoH BLUE input wire to log voltages...

    Converting to Electric over Hydraulic this week

    Interesting on the power lead. The black wire from the vehicle (labeled as "trailer battery charge circuit") comes right off a relay in my F150 and powers the Hydrastar unit and the blue just supplies "signal voltage" from the P3 controller. Seems to work fine from all the run testing I have...

    Mercruiser Trim Issue (not the usual issues)

    Sometimes the little white plastic disc under the solenoid that can get a spec of material in it and prevent that solenoid from working. They pop right out and are easy to inspect.

    Stuck on what to do with mercruiser controls

    Understood. The older boats are not required to upgrade, but smaller open cockpit boats surely would benefit from one, for safety reasons. Was only a suggestion.

    Converting to Electric over Hydraulic this week

    Update: Completed all the wiring and everything tested perfect 1st shot. Battery charges like it should (battery box assy has a status and charge indicator on it) Now to bleed the 4 disc calipers. Only dislikes I see at this point are: 1. Brake fluid resevoir on actuator is pretty small, so...
