Hi,
I have a 85 222ccp with a suzuki DT225. I have trim tabs but the boat has a hard time getting to plane. The bow comes up to where I have to stand to see over the bow. This isn't fun for this ol pirate, because I only have one leg. My mechanic suggest wedges, as the dead rise doesn't permit the motor to go all the way down. The fin on the front of the cavitation plate digs into the transom just above the plug. I'm thinking of getting the ol grinder out and fixing that. Any one used the wedges or got any other good idea's?

I'd like to see a picture of how the front of your antiventilation plate is able to contact the transom. Something sounds a little weird on this set up.

I`ve never seen that either. Wedges do help, but I`m having a tough time understanding; especially with trim tabs, why you are not jumping on plane. What is your engine tachometer reading at full throttle, what pitch prop are you running? Have you drained the inner hull recently. How is the compression on the motor, running on all cylinders. That boat should jump on a plane easily without trim tabs! Lets figure out what is really going on!

I suggest:
1-get a new mechanic. He does not know what he is doing. Yes, wedges can help some boats but you have other issues that need fixed first.
2-drop the motor down until the anti-ventilation plates is even with the bottom of the keel
3-trim all the way down and check hole shot. Make sure the little rod is in the bottom hole.
4-get up to speed and adjust the trim for top speed at wide open throttle. If it tries to go over redline, throttle back.
5-tell us the max rpm you obtained as well as prop specs or prop model number at least.

I agree with John especially on 1and 2.

I second that, we need some pics

Thanks for your help guys. We have 22 deg. temp and its expected to last about a week, so no in water testing is possible.
I'll get some pic's for ya today. The mechanic is a certified mechanic who works full time for a local factory dealer with 30 years experience. My prop is 14 1/4" by 18 Stainless, not sure who made it, but I think Suzuki. Hub is good. RPM's if I remeber correctly where about 5200 at WOT. We just put new plugs in the motor as well, The compression is good and within specs on all cylinders. When I use the tabs, it does come up better but I still have to stand before it gets on plane. It in no way jumps up on plane. I have had boats for most of my life, and I'm 63, mostly in/out setups on cruisers. This is the 1st pure fishing boat with an outboard for me, since my old 16 foot wood hull with a mercury mark 25 and that was many years ago. I have never seen the motor hitting the transom before either.

The motor shouldn't be hitting the transom...the stainless bolt shown on the mount (the stop), I'd move it.
Something ain't right.
No worries...the posse ALWAYS prevails... :lol:
-
I would pull the two side motor mount covers and see if your lower mounts are toast. :? Is the transom solid? It could be flexing allowing the engine to hit.

Guys,
Assuming JD's motor is in full down position, compare the pics:

After you do all of the things the other posters recommend, consider replacing the 12" x 9" Trim Tabs that are on the boat now with 12" x 12" ones. The 12" x 9" that are on the boat now are undersized for your 222 and motor combo. The 12" x 12" Trim Tabs will fit right where the 12" x 9" ones are now and will extend aft 3" more. You will not have to move the actuators (rams) and the larger Trim Tabs will make a difference with your holeshot and bowrise. Additionally they will give better control while causing less drag since they will have to be deflected less that the smaller ones to make the same amount of lift.

Smitty,
Just pull the pin out of the bottom hole and move it up several holes. I'll assume that is what Gran is saying.
That's all that is wrong with the motor hitting the transom. You can now see it in the second/fourth photos.
That will solve the transom problem, assuming the pin's not frozen in place. :roll:
PS.... I run 18 x 9 tabs on my CCP. They pop it up on a plane like an emergency blow on a submarine :o
-
Thanks Guys!
Capt Bob, Those 18 x 9 tabs, did you have to change actuators (RAMS)? I'd like to go to the biggest tab without having to change actuators. I'm all for jumping out of the hole and on plane. That damn bolt is froze up. I'm a bit leary of pullin out the torch and heating it. I guess I'll buy another and move it up and do the transom patch work. Seems the wedges are not going to get purchased, going for longer tabs instead.....lmao. Thanks again for all the help guys.

The 12 x 12s will give about the same lift as Capt Bob's 18 x 9s. And you won't have to move the actuators.

Thanks Tom.
I found a pair of 12x12's on craigslist for 25.00, they are on the way. Now if I can get the weather to co-operate, I can get this part finished.

Tabs are great on these hulls, but I'm with the boys. She should JUMP on plane with that Suzi, tabs or not.
Walk through the advice, especially the pin position and inner hull water retention/weight.
And when you say "transom patch work" where do you mean? Tx.
And thanks Tabman for your presence and professional advice.

I'd venture a guess in that Smitty is referring to the "denting" you see in the photos where the front of the lower unit has been striking the transom.

Better to fill in the dent than to "grind" the plate. :wink:
Just a guess. :idea:
-
Gotcha, missed that.
Thanks CB :thumright:
-
Capt B........You are right on target.. fill in the dent is exactly what I meant. Moving the bolt up, will negate the need to grind the fin. I have an eye on new 12x12 tab plates as we speak. The transom seems fine, but I did pay attention to what JD wrote about his transom flexing under load. I'll have to keep an eye on that just to make sure.
We have another issue with the steering cylinder, hard steering, it was an off breed, not the seastar, So we're replacing it with a new seastar cylinder HC5345. While I'm changing things, whats your opinon on changing out the fluid in the trim tabs? It has the bennett motor and tabs, It was in there when I bought the boat 18 months ago, seems fine, but no tellin how old it is.

Smitty,
I think Aquas in general are, by their nature as a planing type hull, bow high riders. You can see this in the Photo Gallery of both the 84 and 86/87 model pics. My personal experience confirms (at least on my boat) this. That stated, the tabs are your best friend. I'm not sure the actuators are needed to be moved to properly function with the longer planers (unless they use a different size ram) if you change to the 18 x 9 planer but assuming that you gain 6" total length (from 12" to 18") it would move the planer 3" closer toward the motor and quite possibly cause ventilation. That would then require that you would need to relocated the actuators further outbound. That stated, the 12 x 12 would both help overcome squatting and save you the extra work.
I use about 40% down tab and a neutral ( or slight +) motor trim on take off. I find this works very well and at the same time doesn't require jamming the throttle full forward to get on plane and bring the bow down quickly. I'm a big fan of trim tabs and I think you can solve your problem very easily with the longer chord planers. Tabman has already confirmed this and he most certainly knows.
Good luck.
Edit: I'm editing this post to once again give a big "Atta Boy" :thumright: to Bennett's customer service. I, as well as several others here have touted Bennett's service after the product is purchased and IMHO is matched only by the quality of their product.
Once again they have helped me with my tabs (which were originally purchased in 1996) and provided me with both product and advice. You cannot go wrong with this group. If only every business in this country were run like this, customer complaints would be non-existent.
