2 problems

[garagenc]

1: As in the thread I have 2 problems, 1 my trim doesn't work on my 1999 200hp optimax. it was working but slugishly, then it quit working, I drained the fluid and it was a mixture of white and brown color. lastnite I tried to flush with new fluid but when I hit the switch it will only click at the motor. What do I need to do to start trouble shooting?

2nd: Prop problem, This same motor is on a 85 V-20 cuddy and when my son was driving it he said it kept plowing as it tried to plane and then would cavitate and settle back in the water. He said he could get it on plane easing the throttle and using the trim but when the trim wouldnt work he couldn't get up on plane. I went to see the guy at Bay Propellar and he checked the insert while we were there and it held torque, then he and I were talking and he said the 21 pitch was too much for my boat and he suggested a 19. But the 200 hp optimax I have is a counter clockwise motor (left side of boat) he said he didnt have much in used props but he suggested a new 4 blade SS 17pitch said he would sell it for 325. What do you guys think on this?
