Repower 2003

[300R Ally 2+2]

I have a 2003 with an 280 and thinking about repowering with a 4 stroke. I would appreciate suggestions and what others have done to power their 2003.

Thanks!

I saw a guy on facebook with a 300R on his. I never heard if you got it running right. I know quite a few that are running just as fast or faster than a 280, with better fuel mileage than a 280.

How does the 300R weight compare to a 300XS? I've read that the 300XS can work

the 3.2 will work with the right setup
haven't heard how the 300 r is doing on the 03

Has anyone re-powered with a Merc 300R? The 20" is 510lbs (about the same as the 300X)

Fully wet the 300R is 565 lbs. There is one person that has one on an xb2003. I have not heard about the performance, handling or top speed.

What setback is being used on the big motors?

 

[SLOmofo]

If I remember correctly Bill Smith used a hydraulic 4". I have a plate that can be 7" or 8". I wish I could use a smaller one but the way I built the trim system it won't allow less than 7".

some guys with 300xs are still running 14" setback. One guy I know runs 108 fully loaded with trolling motor. I don't know what the other two fastest guys on the east coast are running with their 300xs motors. I imagine you could get away with 8 to 10" with a 300R.

we are 14" back 110 +

 

[300R Ally 2+2]

110....that's flying! Do you have a 3.0L on your rig? how does it sit?

Is this a fishing setup on the 03? What prop are you running?

Thanks!

 

[bullwhipjkg]

Do you run the 34 Triton on your 03? What kind RPMs are you turning?

 

[bullwhipjkg]

35 is on the 03 6000+

last time I run the 02 turned it 5900+ with the 34 still playing with setup

the 03 is faster

I agree with dubmoney. The 300R will probably have to move in on boats that had 300XS motors. It was that way on the 21 XB Prosport I'm running. It was just too heavy on my boat and too far back when I was set at 13.5". I went to 11.5 and it got way better. The motor has so much torque it will spin super big props up, but it wanted to put the nose way up in the air even with tiny wheels for a 1000' race. Loaded or unloaded it was bad compared to my 300XS. When I say bad it still accelerated even with the 300XS, but you could tell it was going to put a beating on it if the nose would come down. I lost about 1 to 1.5 seconds in the holeshot as a result, which as I said made it even in holeshot to the 300XS. To get the nose down I moved my trolling batteries to the nose. It was a huge help but it killed the top end. When I raced last summer I had the boat cleaned out and it still wouldn't put the nose down fast with only a starting battery in the boat for a 1000' race. I had to move the starting battery to the nose to get it to come down fast and launch fast. After the race I moved my setback in and was able to run with all my batteries in the back like I did with the 300XS. I did eventually switch to a lithium troller to offset the additional weight of the motor.

Nice! How do you currently have your 03 setup for boat riding?

 

[bullwhipjkg]

bare boat light rigged for riding this 03 doesn't fish at all just a riding boat

I am going to try this still looking for a prop to turn and what setback I should be running on this set up
