    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...

    4.3 mercruiser no spark at operating temp

    Sounds a bit like your loosing power to the module or pickup. Do you have 12V at the coil when it will not start? If the diode shorted you shouldn't be able to turn the motor off. If its open it would take a long time before the TKS module closed off the extra gas, so it would be running rich...

    TKS 4.3L Mercarb

    Depending on the outside temp it looks good 70 degrees F = 35-45 ohms 20 degrees F = 55-70 ohms When 12V is applied to the leads and module is cold, it will slowly increase in length (no click). Here is the bench test

    What would cause sudden loss of power?

    Yes, the filter causes a high flow restriction, it does fine a low rpms, but higher and under load it needs much more fuel. It also depends on which filter your have, the old stone filters go in the other way

    Mercruiser 4.5 overheating

    No matter what it has reduced water flow to the starboard manifold. Only thing I can see with 4 hoses is with the open cooled system and its for draining during winterization. Where is the rear poppet valve you mentioned? My thought is the check valve on the SB side got stuck and now its free...
