Just saw a test on the new Charger 198 and it had a 23 fury 3 blade and ran 70.
Following
Boatingmag.com has the test and review.
23 seems small. I run a 25 on my 2-stroke. I would’ve thought you could get the rpm’s needed out of a 24
From what my friends are running on the new merc 4 strokes they all are a few pitches smaller than the 2 strokes with same boat.
I had this argument with someone on FB, you need more rpms on the 4 stroke. More rpms is with a smaller pitch prop, you could use the same 25 on the 4 stroke, but you’re not going to get the 6k+ that’s needed.
I’m putting a 4-stroke merc on a 198. Was wondering if anyone has done the swap and if they went with a fury or tempest. Thanks
Hopefully someone has done this and will respond.
From what i have seen the Yamaha SHO turns a littler higher pitch prop than the Mer 4 stroke. Either way try the prop you are currently running to see where you are.
I wish i had and SHO ! My friends have switched from SHO to Merc 4 stroke on same boats and in general the Yamaha turns a slight higher pitch in these cases.
Im running a 200 HP , 3.3 liter yamaha with a ph 2 kit on mine with a 26 tempest and 10 inch jack plate.
I had a 2000 203 with a 2020 Mercury Pro XS 4 Stroke 250 and it ran well with a 25 tempest. So a 225 on a 198 would probably run a 23-24p
