Hi guys, I never post here but at this time I'm seeking for some help identifying my actual gearing. I have a carolina classic 25 with a 8.1 engine with a volvo penta dp d1 stern drive with b4 props and I'm only turning up to 4200 rpms when trimmed and about 3900 when is not trimmed and I'm supposed to be turning 4600 rpms, the serial number tag show that is a 1.78 gearing, I also remove the anode behind the propellers and I also see 1.78 but there is some engraved numbers in the propeller shafts and I've been told that by reading those number I actually have a 1.68 gearing. I would like to know if you can help me with this, the numbers in the propeller shafts are as follow:
3855602 04-021
044
F-12 (R-3) P-3
It looks like if I do have in fact 1.78 I should have a c4 props and that is why I'm trying to find out what my gearing really is as it looks like the gearing could have been changed and everything else, like the tag and housing left as stock.
I would attach pics but so some reason it won't work.
Thanks in advance for any help.
