I have the opportunity to purchase a 1994 Bayliner Bowrider with a Force 120HP. The owner has maintained it in immaculate condition and it literally goes directly from the lake to the trailer, is washed and waxed and then stored inside the garage after every use. Boat and engine have low hours. I really do believe that it has been taken care of.<br />1)Cost is around $10000 USD, including trailer and equipment (life jackets, ropes, skis etc.) (Is that too much...it really is in immaculate condition, and assuming the mechanics test on the engine comes out good...)<br />2)I am new to boat ownership...this purchase would be for our new vacation property and the boat will be used 25 times max per summer season and will always be stored in the Garage (our property is not directly located on the lake)when not in use. What sort of maintenance tips do you have - given the situation...should I just rely on the local boat mechanics for service...What about oil changes (how often?) and type of gas? Spark plugs changed how often?<br />3) Is this engine strong enough for pulling kids and adults waterskiing, tubing etc.<br />4) Any other advice for a possible new owner...
