Mine is 87 sea nymph fish ski... 2011 90 etec
37 mph with 4 people and loaded with gear
You could get the boat and rig it top to bottom for under 20 k including new motor, batteries, riggers and electronics
I own a 1987 sea nymph fish and ski
Put a brand new 2011 90 HP etec on it with new controls/ wiring/ battery
new scotty 2116
new humminbird fishfinder
new fish hawk
new planner mast
Basically everything on it is new and higher end and was in probbably 1/2 to 1/3 of what a 10-5 15 year old Lund would have been
I will give you a suggestion from personal experience.
Buy an older used Hull and deck it out from new motor to new electrics
A 30 year old Hull is better than a 15 year old motor
