I still don’t have my full break in time completed so I don’t want to exceed 6000 rpms quite yet. And I’m limited to 5min Wot at a time. ��

*Update*
Success!! Here are the ending results of my prop tests.
3.25” ptp
Scorpion 15x21 3 blade
WOT rpms 6000
Speed 52-53 mph
Suzuki 150 SS
2003 Ranger 185vx, 2 people full gear and 3/4...

No water pickup on the nose. Thanks for the links provided!

Had my motor moved up and jack plate adjusted to 3.25 ptp from 4.5 ptp. Max rpms now 5300. Currently running a Solas Scorpion 3 blade 15x24. So making progress. Tested with a really good setup guy...

As requested

Will do. Crammed in the garage at the moment but I will take some pics before I head out to my dealer tomorrow.

As part of my set-up I will be adjusting the height of my motor. It is a 2021 150SS (150AS) on a 2003 Ranger 185vx. Anyone know what kind of water pressure numbers I need to stay within?

Same engine and prop I had prior to my repower. My ptp currently is 4.75”. So I’m heading to the dealer to get the motor raised since I’m topped out on my jack plate. Aiming for 3.5 to start out with...

It had a 175 Optimax (2003) running a 24 pitch tempest blade. The dealership mounted the new motor at the same height as the old one. It would run low 60’s. I’m surprised that height setting worked...

Update. Couldn’t get rpms above 4900. The average was more like 4700. Measured my ptp and it was 4.75”. Manual jack plate at max height. Sooo. Taking it back to my dealer to have the motor raised to...

The pad seems to have varying angles. It comes to a V right below the plug. Is that the correct place to take the measurement?
If so it’s at 5”. I left out that it is a 2003 185vx Ranger in my...

Does the proper prop to pad height vary depending on the prop diameter and pitch? I have a brand new Suzuki 150SS and purchased a Solas Scorpion 15.1 diameter 24 pitch prop after calling Solas for a...

Wave,
Sorry forgot to mention it’s on a 2003 Ranger 185vx.

Wave,
Yes it has the 2.0 gear ratio. I’m going to time my hole shot and see what rpms I get at WOT tomorrow. Should tell me which way I need to go or if I guessed right the first time. Once I get...

Anyone know why the WOT for these Zukes have such a wide band? 5000-6000 rpm? Should I be up in the 5700-6000 range when propped right? I had a 24 pitched 3 blade installed (Scorpion). Finally got...

I thought I had a bad coil pack on cylinder #3. I purchased a new one and connected it but I did not mount it to the coil plate. Still no fire. I’m curious if the bolts attaching the coil to the...
