198 Fundeck

I just purchased a used 2004 Fundeck 198.  It has a 115 HP Yamaha and in general we are very pleased with the boat. As usual there are a few niggling bits to complain about.  My wife says I would be very disappointed if I did not have anything to work on.

1. First the steering.  It is very wonky (technical term).  Boat does not want to hold a heading.  High steering effort. Small inputs generate large changes in direction or very little change.  I've altered trim but that seems to have little effect. It is better at high speeds.  Anyone have any suggestions?

2.  Trim indicator on dash worked initially but then quit.  Any quick fixes?

3. The dash speedometer does not work.  The sensing unit is in place on the back of the boat and as far as I can tell it is not obstructed.  

All help and recommendations are appreciated.

    can only help you with #3...there  will be a small hole of the front of the outboard engine (~1/8 inch) that needs to be unplugged....just put in a small drill bit/similar to unplug....Marty

    For #1 You may need to change the trim tab at the engine. Initially my boat pulled starboard. I adjusted the tab 1 or 2 notches and it fixed the problem. If you have a hydraulic steering system, you may need to purge and refill the hydraulic fluid. Its not hard to do, but requires 2 people. The instructions are on the Teleflex website and you can buy a kit with the fluid and the filler hose: [link=]http://www.teleflexmarine...nuals-filling-purging/[/link] Don't know about #2, and mlmeador is right about #3.

    Is your speedometer working off of your outboard or a add on device. Usually it works off of the outboard motor system. If that's the case, then what could stop your gauge from working is the hole on the outboard is plugged.  You should be able to locate this very small pin hole by sliding your finger down the front of the lower unit (the front being the portion of the motor that faces the stern). You made need to check your motor manual to locate this hole. But when you do locate it, you can take a paperclip and push into that hole to clean any blockage, such a muck, weeds or sand. Pushing the stuff in won't harm anything. Hopefully this helps.
