Stingray's are typically fast hulls too. You're 700 rpms short for some reason and I wouldn't think a 19" would be that far off. Something is not right. I hate to ask but how was the boat stored? You could have soaked foam.
Is this a runabout or fishing rig? I'm pretty sure the front one is nothing more than a cooler that drains overboard. If it was a live well you would have more than one supply and or drain.
Mount the bimini so that the rain top can be erected underneath the bimini. That way when a rain blows up you don't have to double up on work. Also the wider the bimini is the more likely it will shed water off to the sides and not into the cockpit if you don't want to put up a rain top.
Not much of a way around it. You have to take the boat apart. Here's what mine looks like after having done so. I lay a foam raft on the sofa seat for protection and remove my engine cowling so I can use the stud and a dowel to prop up the sun pad after releasing the gas springs. PITA but...
Tabs will help, down propping will help, but the real fix is a larger outboard. According to what I could find on the web you only have 1/2 the maximum recommended horsepower.
With autos you're told to inflate to what the auto maker says (i.e. placard on door) rather than maximum inflation on side of the tire. Is this the same with trailers? My trailer placard says 50 lbs. my trailer tires say maximum inflation is 65 lbs.
Is this a tubular steel trailer, c-channel? What do you have? If you truly jacked just one side I do not see how its physically possible the other side came up with it.
Gotta admit I'm lost on this one. Do you mean the hole (at least the bottom one) lets water escape if the bellows is leaking? So if water is allowed to escape via this hole it would be viewable from inside the boat? Am I on the right track? The round hole above is only to vent?
I boat on a deep inland reservoir where bottom strikes are almost non-existent. Strikes with floating debris, however, is very common sometimes big stuff. I've always had a steel prop and it has remained unharmed throughout this for many seasons. This is the main reason I run steel. I don't...
I jack the axles. I put the bottle jack just far enough from the wheel to get the jack stand in between. Drop it onto jack stands as close to the tire as I can and still be able to spin the tire. This is the way it has sat for 18 winters.
2.5 weeks is no issue. Was wondering if it could be bad unstabilized gas if it had sat for long period. Your 21" may not be that far off then. I dropped from 21 to 19 a few years ago and made a big improvement. Wondered why I hadn't done it years prior.
