203 Holeshot Question

[Dehaan28]

I have a 2000 203. With 225 optimax, 3.5 ptp, with a 25 tempest on it. Was out this weekend and it seemed to dog out of the hole, I played around with the pvs plugs and did not change anything. What are avg holeshots for a 203? Could it need new plugs? Something wrong with the motor? What do you guys think?
Thanks

Should be less than five seconds.
Once it breaks over and goes what's your speed/rpms at full power/trim?

[Dehaan28]

62-65 mph and about 52-5300 rpms

Sounds like your missing 600-700 rpms. Make sure all your coil packs are connected. You might be running on 5 cylinders instead of 6.

If it was running on 5 instead of 6 cylinders wouldn't there be a noticeable miss in the motor or no?

Not necessarily. Do you have to peg the throttle to get it on plane? Do a little research on coil packs and opti's.

When was the last time spark plugs where changed...have you ever had your injectors serviced, fuel lines changed, filters changed lots of things it could be.

Is this a new situation? If so, motor needs check up.

Yes I do have to peg it to get it up on plain

I just got the boat in September and it was under proped. I kept hitting rev limiter so I put a 25p on it and ever since I did that it's done this. Taking it to dealer this week

with a 25 tempest on a opt 225, 203 that is set with a 3.5 PTP, you should have no trouble with holeshot, or spinning that prop to 5600-5700 rpm.

I had 3 different tempest 25's...all I could spin to 5600rpms with no struggle.

something else is going on with your motor....and your speed is slow for that prop...by about 6-7mph.

guessing your on 5 cylinders.

That looks bad. Do you have a good Mercury mechanic fairly local? Also, we have excellent folks in the Mercury forums here on BBC. They might be able to point you in the right direction!

When's the last time you changed your plugs?

I just got the boat last fall so I haven't until now!

[Materman2007]

That plug had oil on it maybe bad ring or stuck need check comp.

Again...time to check with a GOOD Merc Mechanic!

And let us know how it goes!

[Dehaan28]

UPDATE: I changed plugs, hopped right out of the hole, 5600-5700 RPMs 68-70MPH. Completely different boat!! The shop I took it too said everything checked out just needed some new plugs and filters.
