    VP 2007 3L 135HP engine oil options

    No, not really It is one of the very few cheap high zinc oils. You need zinc for your flat tappet motor

    looking at a 1990 thompson 260 fisherman

    the boat is 36 years old. consider it has rot until proven otherwise. you have to drill test to determine rot in your transom and stringers

    Keep blowing my starter solenoid up.

    if the purple wire reference to the alternator sense pin calls for more juice, that alternator will try to make that sense pin voltage go above 13.8. as stated, depends on the battery and condition of the wiring.

    Need different prop for pulling

    You are being your own worst enemy here.....Mash that throttle on the holeshot. It's not about speed, it's about getting that large mass moving The 5.0 is still too small for the boat

    China propeller

    some of the prop manufacturers use off-shore sources. without doing digging, it may be as good as other props. or it may be a really bad knock-off.

    VP 2007 3L 135HP engine oil options

    your motor is a flat tappet motor. I would stick with dino squeezings high in zinc, like Rotella T4 15W-40 as for the outdrive, use a marine gear lube that meets volvo's requirements.
