Official (1998-2002) 310 Sundancer Thread

Hi. Can anyone give me advice about distance and speed. The boat is a 2001 310 Sundancer with twin Mercruiser 350 MAG MPI (350 cu in, 300 hp, 5,735 cc, V8), 300 hrs, well cared for with regular servicing, but up until now used only for cruising on Ontario - Lake Huron, specifically the inner channels in the Parry Sound-Waubaushene area. I want to take it across Georgian Bay from Vic Harbour up to Little Current/Killarney. Does the boat have that reach in one run or do I need to do a refuel or engine cool stop at Parry Sound or Tobermory? What would be an optimal cruising RPM/speed? What would be the fuel flow at that optimal cruising setting? And, if anyone knows, what would be the best way to take the boat to Mackinac Island from Vic Harbour?

I would cruise about 22mph. I was able to run 110 miles on one tank. May have been able to push it, but gauges were not great.
 
Ah. Thank you. I presume you are not referring to Nautical Miles. And, when you refilled, approx how many US gal or litres did you need?

Figure a mile per gallon
Boat holds 200 gallons of fuel ,100 for each motor
 
I want to get a new set of double-braid lines before my 310 gets here later this week. I'm curious what diameter dock lines you folks use. I've always found the 1/8"-of-diameter-per-9'-of-boat-length formula to seem a bit light, and I think 1/2" lines would appear quite small on the big cleats of a 310. Do most people use 5/8"? With the cost of double-braid lines, I want to get it right the first time.
 
Does anyone have good guess to fuel burn per hour for my 350 merc cruisers?

Also my port fuel tank would barely fill today? Fuel guy seemed to think fuel line was not at steep enough angle to the tank... has anyone heard anything like this?
Thanks for your help
 
I need to repair or replace one of my windlass foot switches. There doesn't seem to be any way to access it from below, other than reaching across the underside of the bow through the anchor hatch opening (which is not very feasible), but there seems to be resistance when I try to pull it up through the hole in the deck.

Can anyone tell me the best way to get access to this switch so I can remove it?

Assuming someone didn't 5200 it, you should be able to remove the entire switch assembly from the top.

I've always used ⅝ on mine.
 
I'm sure this question has NEVER been asked!! If it has, I wasn't able to find the answer... Bottom Paint? How much will I need for my 2000 310?
Recommendations? I used to use Super Ship Bottom but the poor fellow that owns the company in Florida took ill and it is no longer in production.

FWIW,
Just had a coat of bottom paint on my 500 done yesterday and they used less than 3 gallons including the mechanism for my swim platform.

I used https://www.seahawkpaints.com/product/cukote/, but would think it covers the same.

Hey Shaps! Long Island... North or south shore? I'm in Center Moriches. Still a bit chilly here on the south shore. I was in Syosset yesterday for work and they are actually getting leaves on their trees. Going through my list of To-Do's. This is my first time bottom paining my new to me 310. Thanks for the reply!

Boat is on the South Shore, in Lindenhurst. I'm a North Shore guy.
My boat is going in Saturday. Can't wait!

Spent a long weekend at West Hampton Bath & Tennis last year, went on the outside to Shinnecock and worked my way back. I would love to run inside, but there's no water by you! :eek:

My previous boat was a 28 Penn Yan that drew a whopping 22" of water. That boat was made for Moriches Bay. When I bought Civility, it was in the Peconic River at an awesome, no frills marina. I was able to spend October and November playing on the Peconic Bay. LOT'S more to do / see than Moriches Bay. I have a ramp in my neighborhood so I drove her around in December. All the buoys had been removed by this time. I SHOULD have went outside. I stayed inside. Even with two competent lookouts, Two competent GPS units, I still shined the props twice. Nice homes at dune road, but 4 hours to run 25 miles! Needless to say, We're going back this year. I could put her in as of today, but it's still chilly. Maybe a couple more weeks.
 
I'm new to the 310, so pardon the newbie questions. Can someone tell me where the sea cock is for the A/C unit's cooling water? I've searched the manual and the boat and I haven't been able to find it. Thanks
 
Hey guys so I reached out to sea ray and got no response. Wanted to know if any one knows the swim platform weight capacity? I added dinghy davits that stick out and want to make sure I’m good to run in rough water with no worries. The dinghy and engine both only weigh 200lbs. But with that weight past the platform edge I want to make sure I’m still good.
