    2003 Volvo GxI in my 6500lb cabin cruiser (four winns vista 268). Weird bog / deep exhaust sound when hitting the throttle: Last couple of times out, when I’d it the throttle hard to launch, the motor starts to rev and then a horrible bassy exhaust-type OOOOOMMPH occurs. And no power. If...

    Any easy drop-in replacements for the 230B with an SP outdrive?

    I’d love nothing more than some more power on my houseboat. The 230B motor runs fine. And top speed is 8mph with a tail wind. Outdrive is an SP-C. Are there any motors that will bolt right up/in that would NOT require a transom modification? I don’t want to take the boat out of the water...

    ECU reprogramming benefits?

    Weber conversion throttle cable set-up

    Previous posts suggest that some of you have done the conversion. I was trying to find all the photos because I want to see how to set up the throttle cable. Any suggestions? I have spent more time messing around with that that anything else. Thanks in advance!
