Yeah, losing voltage to the coil when cranking. Only place that can happen that I can see is at the ignition switch. What do your gauges do while you're cranking?
Usually the issue is in the cable or adjustment, or a couple of other culprits not involving the gear case. What issues are you having?
The current specs will give you a ballpark, but won't be exact. Especially if you aren't sure that you're currently propped correctly (you need to know your...
Yes, if the yellow/red wire stops supplying voltage, you essentially don't have your ignition key in the start position. I mean, if you know you have a wiring problem, seems like a good place to start regardless, no?
Yes
Ratio of turns of prop per engine revolution. In a 1.98 the prop turns almost 2x for every turn of the engine. Essentially like a lower gear in a car
Your engine revs will be off, your boat will perform lousy, and you can damage it over time. Yes, you need to reprop
Like achris said, it...
You're looking for wood chips--what you'd expect to see if you drilled into a fresh 2x4. What you don't want to see is anything wet, mushy, or saw dust-y. Drill low down, particularly around the transom cut out and around any penetrations (speedo pitot, foto finder, etc)
Wow, bold and in caps? Of course!
Access to the underside means that you can get underneath the deck and get around the bottom of the hole, get tools under there, etc. If there's a hole, you can pass something through the hole but that's it.
Still might not be putting out enough presure at high rpms. Did you ever check the pressure?
That's for the alarm system, it was optional for a while. Think it became standard at some point.
Might work in an application where you're trying to fill a hole with some rot around it though, right? My transom had a pitot hole that rotted around the screw. I drilled larger hole from the outside, scraped out the edges and filled with poly resin last year. Drilled/pulled the resin plug out...
So, a heavier car with a bigger engine *in the city* gets better mileage than a smaller engine in a lighter weight car on the highway? Sorry, not buying it...
