So I'm looking at getting an Alweld 1752 flat. Was first thinking a tunnel hull with pods to help protect the foot. I know there are mixed feelings about tunnels and flat bottoms, so I'm keeping the idea of no tunnel open for now. The problem I have with no tunnel is with a motor with power tilt & trim and you hit something it won't kick up or kick up as easily if it didn't have power tilt & trim. Now one of the motors I'm considering is the Merc 60/40 four stroke jet. I was on the Merc website and it looks like you can get it with either power tilt & trim or gas assist so you could leave the motor unlocked. The gas assist looks like the way to go if one goes without a tunnel, that way it would kick up if you hit something.

I know that you'll lose the ability the tuck the motor in at take off then trim up while on plane, but wouldn't the ability to leave it unlocked with the gas assist be better after you found the best setting for trim with your load for the day? That's what I currently do with my Merc 25hp prop now, I don't have power tilt & trim. Just tuck it in if I'm by myself and adjust the pin to other settings when the load changes (more people etc...).

What do you guys think??

Or you can get an aftermarket tilt/trim to go with the motor without factory tilt & trim and have the best of both worlds. You'll have the breakaway transom clamp on the motor and the fine adjustment of tilt & trim from the aftermarket tilt & trim unit such as a Panther 55.

That unit has a 7" setback, that would not be a good combo with the jet.

I've run both but generally I have no need to trim it other than when I pull up to my dock. I have a tunnel and I need to run the motor tucked all the way in (I'm by myself 99% of the time) but I've never hit anything yet. Tilting the motor was not the easiest thing with me weighing around 150 lbs so I put power tilt/trim on mainly for that purpose. If you have other people in the boat a high percentage of the time, the fine tuning of power trim really works well.

Looks like your running a 60/45, did it have the gas assist before you put power tilt/trim on?

Yes, I bought a new tilt and trim kit and added it to the motor. It wasn't exactly the correct year kit so the relays aren't in the right location but everything works fine.

The Merc 60/40 I'm looking at weights in at 267 lbs, do you guys think the gas assist would really help or assist in tilting the motor up. I've read on other forums that guys with gas assist on motors of this size say that they can lift the motors up easily with the assist, just push down on the tiller while grabbing the back of the cowling, no problem.

I just think the ability of the motor being able to kick up when you hit something would be much better than locked in with power tilt/trim. Am I thinking wrong on this guys??

I only have gas assist on my old merc two stroke 60/40 and I'm able to tilt it up with just the tiller handle if it didn't have the tiller and only had the cowling to grab it would be hard. I like the gas assist it has allowed my engine to kick up a number of times when I've hit a log or something else which seems to be unavoidable sometimes.

I have the tilt assist on my Evinrude and it has the break away feature you are talking about. I've hit stuff and it works great popping up to help reduce damage. Actually I've hit stuff so hard the cowl has come flying off into the boat but that is another story.. big reason I wouldn't want a tiller.

However, I'm in the process of converting to power tilt and trim now after riding with a few friends who have it. The ability to tuck the engine under is GREAT when you overload a jet. Sometimes I fish with a loaded 25 gallon bait tank and it can really hurt performance. Having the ability to trim down to get on plane and then back up for top end would be great. I was under the impression the power units would unlock as well. That could be a deal killer.

If your boat will be setup for a pretty consistent load out then manual tilt / trim will probably be fine.

Oh and with PTT you trim up and blow a stream of water all over the place...thats a plus right?

I have a friend that has a Merc 60/40 four stroke with power tilt/trim and there is no UNLOCK feature that I can find. The hydraulic piston goes up to the motor where it is connected with a large pin, no way to unlock. Now I've heard if you hit hard enough the impact may over come the hydraulics and the motor may come up, but that's going to be a hard hit they may cause damage to the foot I would think.

His motor is mounted too low and the leading edge of the foot is an 1" or more below the bottom of the hull which causes a host of other things that need to be dealt with. The way it is now he scared to death to run it very shallow because he may snag a log, rock or plow the bottom on riffles and with the motor locked that would be very bad.

After seeing his with power tilt/trim it had me thinking about the gas assist after I saw the option on Merc's website.

I can attest that having the outboard unlocked helps a lot when you have one of those intake grate bending underwater impacts. I'd like to have PTT for when I have a heavy load but I'm definitely rethinking it now. I guess that is another advantage of running a tunnel hull.

According to the service manual for my engine the PTT models have an impact relief system built into the hydraulic cylinder. Here is the page from the manual. I don't know about other engines.

On a 1752, without a tunnel, you should see speeds of 30+, if it is set up correctly. I have seen where impacts at lower speeds, where the motor was unlocked, flipped the motor into the boat. Although rare, it can happen.

I will never own another jet without power trim/tilt. When properly set the lip will be above the bottom of the hull, most impacts will contact the rear half of the shoe. While running on plane you will be trimmed out and the shoe should be almost level with the hull. It should slide over logs without issue.

On plane with PTT, if you think you are going to hit or it gets really shallow, you can bump the trim up past level for short distances and most of the time clear without the shoe contacting.

As was already mentioned, with it you take off with it tucked under and trim out as you come on plane. Best of both worlds, you don't have to constantly manually adjust to different loads for takeoff or planing speeds. In heavy chop you can bump the trim down to pull the bow down and absorb some of the impacts. When you need to plane out fast with a heavier load you can trim out to almost level before you take off. This causes the bow to climb out of the hole and on top of the water faster, then as the bow gets on top you can trim down to raise the transom up and then trim up slowly as you gain speed. This is a trick I used when I was under powered with the 115.

Plus it makes reverse a little more effective, it doesn't allow the motor to kick up when you put it in reverse. You can stop in about 2 boat lengths if you have too.

Resale value, easier to sell and worth more with PTT.

PT&T on my 60/40. I also have a flatbottom tunnel hull. My foot has taken a few licks. When I'm at risk for an impact I trim all the way down because I want the leading edge of the foot tucked in. Don't think I would ever give up PT&T.

Seems to me you'd want to trim out so the foot would be higher?
