i have a bayliner explorer 26ft with a volvo penta 130 4cyl 270 leg from the early 80s and just wondering how fast it should run?? it runs at about 7mph and wondering if i increased the pitch of the prop would it go any faster? just feel as if the engines revving its head off and going nowher. any advise is appreciated thanks

With a healthy motor and the right prop it should be able to plane.Check the prop size,should be on the barrel or under the prop nut.Be sure it is running on all cylinders.
Is the carb opening all the way?We need to know the rpm at 7 mph.
Without the rpm and speed no way to know what is going on.

Can't help much on the tach except to be sure all connections are clean and tight.
Also on the back of the tach there may be a knob note its position and rotate it a few times to clean the contacts and set it back.

I don't know about the duo prop except to say I'm sure its a major conversion.
I wonder if its even available on a 3.0.
You might post this question on the I/O section.Its more a outdrive Q than prop.
I'm sure we can get your healthy boat to do well.
