Without knowing the type or HP of engine or the length/condition of the boat this is hard to answer. I own a 1980's marlin ski boat in above average shape and I paid $3,000. Mine has a 115 hp Mercury outboard, came with a trailer, skis, life jackets, tubes etc. and runs perfectly. Goes about 40mph.
about $140 depending on the condition
about $350.00 + or - depending on condition
Depending on condition, about $225-$250.

Your Marlin model 989M2 will bring between 75-150 dollars based on how good the condition of your marlin is.
you would need to supply a serial number and model number,along with the condition of your marlin to get a value.
The answer varies significantly based on the condition of the boat, engine hours (and rebuilds), and location. For a boat in very good condition (kept indoors) with an engine rebuilt or replaced in the last 500 hours, I would suggest around $4k.
