    How often do you have your motor tuned up? What would the average cost be for a tune up for a 9.9 4 stroke Yamaha. Note I said average.

    Once a year. Whatever the parts cost.

    Check compression
    clean or replace sparkplug(s)
    gap sparkplugs
    lube all zerk fittings
    lube shift and throttle linkage rub points
    check and adjust timing
    Change lower unit fluid
    If gear lube looked milky replace seals in lower unit.
    Sandy or silty waters, replace water pump
    if pressure is visibly dropping.

    Get the phone book out, yellow pages, outboard mechanic
    tell the shop what you want and get a quote.
    Call several shops in your area.
    Prices will vary a bit, depending on the shops workload.
