Re: Please help

I understand the concept just fine.
I'm thinking the original poster doesn't.
From his explanation it sounds like he's trying to run with the trim 3/4 up and wondering why the bow stays in the air.

No I really don't understand what trim is, if you wouldn't mind I would love to know if you have time.

Here is a pretty good explanation. http://www.clubmarine.com.au/internet/clubmarine.nsf/docs/MG19-2+Technical

Re: help

more information would help... as in when are you talking about, what kind of boat, etc...

Re: Please help

How long have you had the boat? Has it acted this way the whole time you have had it? Can you call the previous owner or dealer and ask them what they did when it acted like that?

Not all Volvo Penta 270 drives have operator-adjustable trim. Most just have tilt for trailering. The drive angle when in forward is adjustable I think with a removable pin that can go into different holes. There is also a catch release I believe for manual tilting. If that catch mechanism is messed up then perhaps the drive is not all the way down and latched and is at such an angle that it does a "boat wheelie".

What happens when you go into reverse and give it some throttle? Does the drive try to tilt up and the prop come out of the water?

Re: Please help

Don't put a fin on the drive. The boat should not behave the way it is being described, spend the effort on the drive itself. A fin would make it even more dangerous to handle when turning once you ever did get up on plane or get the bow down enough to try to turn.

What year, model and length of boat is it? Do you have an operator's manual? Do you know Volvo's series number for your engine, the one that starts with "AQ"? If you can find out the AQ number then you may be able to find an operator's manual for your setup on the Volvo Penta website.

Re: help

There is another thread topic "Please help" from the same poster about the same subject. It has more info. This 'un here should be merged or deleted I think....

Re: Please help

newbigguy,

(Some of this is redundant after reading Maclin's posts, but I am leaving here to emphasise the need for this info) Can you describe the boat for us? Length? Configuration? Year? I am guessing less than 200 horsepower, so depending on boat size this could be normal. Definitely need to learn how to use trim and tilt (kinda same thing, only a little different) The drive itself needs to be all of the way down in this case. Also, is there any weight other than people you can transfer to the front of the boat? Or simply get rid of? Weight is a killer on boats.

Also, what is the condition of the bottom of the boat? Clean? Smooth? You mention towing, so I assume this is a trailer boat, but it is still possible that you have a problem with the bottom. Also it is very possible that your engine is not running right, so the necessary power to push her over on plane is just not there. Also, it is possible that it is propped wrong. A prop with too much pitch could also cause this.

And finally, I agree with Maclin about the whale's tale, or hydrofoil. We need to determine what's really happening before we stick a bandaid on that could introduce new problems. If you need some help getting her to plane, the right way is with trim tabs, but again let's worry about that after we determine if what you have is right as is . . . Good luck, we'll get you through this, but please give us as much info as possible. Long posts are OK if they are full of relevant info.

You are in the right place, welcome aboard!!!

okay guys it is a 17' 1972 orion with a 302 ford inboard, and a 270 volvo penta drive. The motor is in the rear of the boat. yes it is trailored, the bottom appears to be nice and smooth. If you need anymore info please let me know.

in reverse yes it trys to come out of the water and does sometimes.

Re: Please help

Sounds like the trim angle locating pin is missing, or the tilt latching mechanism is broken and keeping the drive from going all the way down and locking to the locating pin.

The operating manual will have the info you need.

Do you know the AQ number for your setup? AQ190A's were produced in a later era, I have only seen references to them having a 280 drive. But the manual will show the adjustments and operation I am referring to.

Form the Volvo Penta site link below set the number of cylinders to 8 then the range of years to include your boat and do the pub search. The AQ190A is the most logical one as it is a Ford 302/351 but it shows a 280 drive. The rest are GM V8's it seems......


http://www.volvo.com/volvopenta/na/en-us/marine_leisure_engines/parts_service/publication_search/



You might also try looking at a V8 from that list that is hooked to a 270 drive from that era even if it is not the Ford 302/351 engine, and look up the 270 drive operation.

Re: Please help

A 17 footer with this engine should not have planing problems. We need to continue to look at trim, but this may also be an engine problem.

Can you get us some pictures of the transom and drive, with the drive all the way down and from multiple angles? This will help us tell you if the trim angle is part of he problem.

 

[Maclin]

Re: Please help

Here is an excerpt from one of the manuals with a photo and text describing the manual trim angle settings. The transom is on the right, the leg is on the left. The adjusting pin runs all the way across the drive into the other side, that pin is also what the locking pawl from the leg catches on, the locking pawl and mechanism is not visible in the photo. If the drive is not latching onto the pin then the trim angle will be way too high in forward and the drive will try to lift up in reverse if enough throttle is used.

Re: Please help

270 out drive with tilt & trim is rare.
'Maclin' give correct advice on altering the out drive 'down' postion. You have to do this while still on the trailer. You will find a long pin that can be removed and put in other positions (holes).

Re: Please help

Where did you got this boat from? If a dealer/marina(doubt it by the boat age) go back and ask them all these question. If a private owner try to get in contact with them. We can help you here, actually, you have been given great advise but the previous owner can cut your learning curve greatly because he can see what you are asking us instead of us trying to figure out what you are trying to say. If the above is not an option photos and videos (if possible and practical) will be of great help.
