Author Topic:   Power Jackplate for 13'er

David Ratusnik posted 10-29-2002 07:44 AM ET (US)
Gentlemen- Pic 56 has a 13'er with a standard jackplate installed. Real nice. I've looked at the Cook Manufacturing web site- seem to have nice manual and power jackplate units. Who else makes jackplates ?
We need one to handle a Johnson 48SPL. If anyone has a preowned manual or power jackplate unit that they wish to part with we may be interested. Thanks David

The most popular power (hydraulic) jackplate here in Florida is made by Bob's Machine Shop in Ruskin, FL. It's used as a factory option on many top brand flats & bay boats, and I have heard nothing but good things about them from people who own one. They make a small model with a 3" setback that would work well...they are sold factory direct for $595 I think. Obviously a manual plate would be cheaper, but if you want a power model this is the one I'd get. Do an internet search, you'll find them.

Is their any reason that you want to put one on your 13ft, I can not see too many benefits?

bone12- My friend would like his wife to be able to use the boat independently of him on occasion- that includes lifting the foot out of the water. Therefore, the power jackplate. Also, he would like the motor set back 3-5" away from the wife and kids. Finally, the jackplate will permit the shaft to be adjusted for flats fishing (big here on the Banana River) or going into the Atlantic thru Port Canaveral where the longer shaft may be useful. David

Uh David....power jackplates will not lift the foot out, only up. It will give max of 5-6" verticle lift. the setback is there but without PTnT I would get the CMC power tilt lift.

Biggs- Thanks. We will go back to the CMC web site and study the power trim/lift set up. Also, we have found Bob's Machine Shop site and will see if they have a similar system. Appreciate. David

you can get the same shallow water ability with power trim and tilt. If you want to get the motor further aft then go with a cmc add-on power trim unit instead of the jackplate. you can only trim or jack a motor so high for shallow water, or you will need a lower water pick up or nose cone which will rob speed.

seems like a lot of extra weight to add on the tail of a 13 - I have a fairly new 25 Johnson with no T&T on my 13, and with 2 adults on board (on rear seat) and heavy battery, if we stop suddenly from full throttle, about 2 gallons of water comes over the stern. My 13 is the low transom (1970 model), so perhaps that's the difference with yours...? AND my boat is NOT waterlogged (it's very lightweight with no gear/motor in it). Anyway, I'd probably just go with T&T because of weight and the extra stress on the transom when you have setback. I just wouldn't deviate from the original recommended design. Best, Mav

It sounds like you're headed down the power trim route instead of the jackplate, which is fine. But if you do want to go the jackplate route, here are some additional thoughts:
I would strongly advise AGAINST an aftermarket nose cone/low water pickup. It is not necessary at all to have an aftermarket nose cone or a low water pickup to benefit from a jackplate, unless your plan is to trim the motor almost completely out of the water at high speeds. With a jackplate you can still trim your motor a couple inches higher at planing speeds without the low water pickup, and you can trim your motor significantly higher at idle speeds on shallow flats. A jackplate is more effective than power trim for doing the latter, if that's your plan. I would agree with the suggestion of a water pressure guage, but that is a good idea with or without a jackplate.
Everyone I know who has had the aftermarket nose cones/low water pickups has regretted it, they do not hold up to bumping bottom at all. It seems like half my marina runs a Bob's jackplate, without a low water pickup, for flats fishing Tampa Bay.
I would be reluctant to go with a big setback on a small whaler...this changes your static trim & also adds stress on the transom. If you do a jackplate, I'd go with the 3" or less setback.
If all you want to do is to be able to trim the motor out of the water, I would agree that power trim would probably be a better bet than a jackplate. You can use Power trim to raise or lower the bow & improve the boat's ride with power trim, which is very useful.
