Title: Jack plate for Osprey 170
Post by: Anonymous on December 10, 2007, 08:23:24 PM

I just purchased a 1987 AS Osprey 170 with a 1987 Yamaha 110 HP on a Flats Jac hydraulic plate.  The motor has a 21 pitch stainless propeller.  The motor does not work and I'm replacing it with another Yamaha 110 (a 1997 unit).  I'm inclined to sell the jack plate and (apparently matching) propeller along with the old motor because I like simplicity and tend to be cautious re speed in very skinny water.  Are there major pluses or minuses regarding the jack plate that I should consider before making this decision?  Thanks.

Jack plates are handy in shallow water but if you aren't careful you can burn up a motor due to lack of water if running with the motor jacked up.

Ditto on JJ's comments.  If you don't have a low water pickup installed on the motor, a jack plate can put the pickup out of the water and you out of a motor!

Thank you, John and John.  I've decided to keep the jack plate for a while and explore some of the shallow backcountry in FL.  I'll certainly use it carefully, keeping an eye on water cooling....I want the new used motor to last many years.

thanks again.

Welcome aboard MM  :!:  :!:
And welcome to the ever growing 170 family.  She'll float in less than a foot - probably shouldn't be in water that skinny unless you're just floating anyway - you'll tear up everything in your path  :roll:
Have any pix?
