If your Alweld 16X48 is the VEE LA model then we have the same hull. Not sure but a guess for a stripped down hull weight would be 450 to 550 lbs.

I am sure someone will find a way to trick cpu and then find a way to open air intake, run bigger injectors and open exhaust but its alittle more involved then the older motor where you just change a few parts and make adjustments with screw driver.

You're talking serious cash with cpu work and bigger injectors. If you want to hop up a motor a tldi isn't for you. Get a merc 40 or a tohatsu with carbs on it. The days of hopping up new outboards is pretty much over. Buy a new motor, put a tach on it and prop it right and work on the setup. The fuel efficiency a new motor gets should make up for not being able to hop it up.

Where on th motor is this restrictor i have a Nissan 40 that's on a 16x36 wellbuilt an it cruises really good!!! I would like to check this out see what kinda of power i will get....

I would run by Lake Area Marine and talk to a guy in the shop

The restrictor trick doesn't work with all motors correct?......

only ones I have heard of doin this on is the TLDI motors, what motor are you wanting to try something on

[Miketrout]

different animal, you can change carbs, reeds and exhaust work and get more power pretty easy. I work with a guy that has same motor as yours on a 1648 rebuilt that runs 47ish, the motors we are talkin bout are the new fuel injected TLDI motors.

K i will keep that I'n mine I'm running about 35 maybe 40 buy my self it's pretty legit I'n shallow water also

Old thread I found in a google search engine i want to revive.

I've got a 2010 Tohatsu 50 hp TLDI short shaft tiller handle on a 2011 15x52 alweld Vee La model.
Stock aluminum 11.1x14 aluminum prop on GPS is 39.1 mph.

I'm bringing this thread back to life because i want to know can i yank this restrictor plate out my intake and get more ponies out of my 50 motor? I have tried shining in with a light but like how far into the throttle body does this plate/cone go? is this plate in there loosely once you remove the screen?

Can anyone post a picture what this cone looks like once it is removed??

I plan on this summer getting a better prop, someone I know has a few that will let me try out before i buy. I'd really like to see 50mph but not sure it is possible. There is a guy on youtube and boat racing facts that claims he took a 14ft weldbilt with the 50 TLDI and got it to run 63mph with a low water pickup and a clever 12x23.5 prop I think it was if anyone want to know really how fast these motors are.

Thanks
Chris

So what you're laughing about is i need to get me a merc? Got news for ya the older 2 stroke Tohatsu when built and probably run faster then the mercs that are built

Get your bloomers out of a wad and read the whole thread and hopefully you will understand. And just a little FYI the older tohatsus won't out a Merc.

The 50 doesn't have a restrictor. The 40 and 50 share the same block so the 50 is restricted to make a 40.

You're saying the carbed 40 tohatsu can be hopped up to make more power than a carbed 40 mercury?

[chris3298]

What do you honestly think the 40 2 stroke merc will produce Max horsepower after you do the 60 carbs and all?

Like I said this is my favorite thread. It can make laugh no matter how bad of mood I'm in.

A 40 tohatsu is 45 cubic inches and shares a block with the 50 tohatsu, so the biggest carburetors that can be put on are from a 50. Put the 50 carbs, intake and exhaust and you have a 40 making 50 hp. Got to do port work to get higher. A 59 cubic inch 40 mercury shares a block with a 50 and 60 mercury. Bolt on 60 carbs and intake and you have a 60 hp motor without touching the internals and it makes more torque than a 45 cubic inch motor.

Both are fine motors, but the mercury has more potential.

Thanks Scott, I'm gonna end it here before it gets outta hand and becomes a pissing match here. Some people are hardcore merc people but from my research I think maybe a tohatsu can probably produce more then a merc. This I heard from people who are hardcore racers that race mercs who have even said it may come to a point they will switch to a tohatsu because they produce more to win races

Ok. I really don't think you can go wrong with either motor, just whatever you're looking for.
