    Low priority but

    Can we happen to make this little (very little) close mark a tad larger? Open the pic, look and try to close it using a touch pad is real hard, even a mouse is touchy. Sometimes I just give up and arrow back and then find the thread again Low priority but would sure like it if it was a tad...

    350 Mag fuel pump cuts off intermittently

    I'm thinking a bad connection, either on the Green wire between Pin A19 and Relay pin 86, or the fuel pump ground (not shown in pic). Could also be a bad connection on the hot side, but would start with ground on fuel pump first

    Lost gas cap

    Could use a measurement across the opening, but it looks like the standard 1 1/4 inch fill cap. Perko makes one, and Seachoice has a chrome replacement. Iboats has the whole fitting, but nothing except yam for cap, found the seachoice cap at walmart

    1988 Mercruiser 165 4 cyl wont start

    In that case the idle jets are probably clogged up, so it needs to be taken apart and cleaned. Need some fine wire and feed it thru the idle circuits

    6.2 mercruiser no power under load

    Guess they need to change their manual 31 (5.0, 5.7, 6.2) because I'm seeing 43 psi at 1800 rpm, the V6 manual 32 shows the same

    I have to take my gas tank out

    Only boats I know of that have wiring diagrams are the high end ones, the regular ones don not. Most use the standard lay out and add more for accessories. That said the boat probably wouldn't need much more

    Crossed the battery terminals

    It probably is the ECM, but look for 12V on the Pink/White wires on the injectors. I think the Gi uses the MEFI ECM and if so, use a LED and paper clip on the dlc as shown to see if any codes show up. Install and then count pulses

    New user , engine swap need electrical help

    Below is a 3.0 but wiring is the same. Need the purple wire to go to one side of the switch. Look around the motor for a banana plug not being used, if its purple that's your wire. Next the distributor should have a plug on the right (see pic) with 2 short wires and one longer one. The long...

    No power to guages

    Would follow the red/purple wire back to the fuse and is probably an inline fuse This is your issue There is a 90 amp fuse on the starter post, it looks square and is there to protect the alternator. Put meter on the starter post and you should see 12V. If 12V is there, then check for 12V...

    New poster but not new poster

    Been here some time and wonder how many sign in as a brand new poster but actually have been here a long time under another name? Doubt anyone will admit, but for me the dead give away is a first post about doing something dumb, or making an off the wall comment to help back up another post...

    Trim limit switch wire confusion

    They might, I haven't been around a 470 much. The newer model trim design uses 3 wires (main power, up and down), and the pump is grounded. The double blue/white would go to the trim limit switch on the drive, and the other side would go to trailer up function. The trailer switch is used to...

    my baja boss 272 it very very hard steering

    In most cases the cause of hard steering is the power steering pump. It can also be the hydraulic ram or adjustment. Look at tube where the cable steering is connected and see if the slots are straight up and down as in the pic ( d )

    Alpha One Gen 2 alignment

    If your mounts are soft they can still be adjusted so the alignment is true. If they are soft, then when the boat is operated stress will be created on the coupler with the motor moving. If you have or can get the use of a micrometer, measure your alignment tool. Many auto parts stores have...
