Do’s and Dont’s of repowering 2400TE

[HoustonHurricane]

In the market to repower my 2007 Pathfinder 2400TE.  It’s got the original Yamaha 250 HPDI on it.  Looking to hear from those owners that have repowered.  Manufacturer, HP, Prop

Has the weight of a newer four stroke changed the ride/functionality of your boat?

Most people put 250 SHO’s on a 2400, if you need a little more top end you can have it tuned.

250 SHO would be my choice and of course I’m running one on a 2300, running Powertech OFS 4R 21 pitch,  lots of buzz on Mercury Bravo 1 22 pitch and Yamaha Saltwater series both 4 blade, you should see a gain in MPG.

250 SHO but would look into the Zukes before I pull the trigger.

I looked at both Yami and Suzuki.  Went Suzuki as it was a much better deal and the reviews from the commercial guys that use them every day was stellar.

Thanks looking at a 2017 Suzuki 300 with about 300 hours, but was concerned with the additional weight on the transom.  I think Zuk weight is listed at about 630#’s, or about 10%+ more than Merc and Yammy SHO.

Thanks Chief!  No issues with the weight on the Zuk?  Didn’t change the ride much negatively?

Same on this end lots of commercial folks and guides running Suzuki, their a good engine as well.

I cannot see any difference in the ride.  i went from a 150 VMAX to a 200 Suzuki.  Only 18 lbs more, less of a difference if you include the loss of the oil tank.

I know someone who repowered a 2004 Pathfinder 2400 from an 25” F225 to a 20” shaft 250SHO. all he did was add a 10” setback jack plate and bolted it on.  It ran mid 50’s wide open.  Saved a lot of weight going from the F225 to the 250SHO.

Mercury makes those light V-6’s up to 225 hp. Check the weight on them. 
The new 4 strokes were heavy on the 19, 22, and 24 V- models. The XL hulls had extra flotation to accommodate the weight.

Make a chart of the weight of the original motor and oil gear, then the weights of the options.. See what you are talking about in todays motors.

Many owners moved batteries, gear, and/or coolers forward to keep the decks flush and draining properly.

All 250’s Merc provides 85 amp alt, Yamaha 70, like MM states rebalance may be required to keep the boat draining properly

XSPro 505

SeaPro 527

SHO 529

The 3.4L V-6 motors are said to weigh 475# on the Mercury site. That’s not far off from the HPDI you are replacing.  It is only 225 hp and not the 250 from the strong HPDI.. 

I just looked and the old 250 HPDI weighed 550 lbs.. 

Let’s see if anyone has input from their repower.. ?

I agree....get the engine you feel is best...and you can move alot of weight forward to compensate....
