Hi list, We are the new owners of a 98 Hunter 310 and have a number of questions. What is cruising speed and cruising RPM? What is the gas consumtion? The wheel has about a one inch play in it, that is you can move the wheel one inch without the rudder turning. Normal, or can it be adjusted? Has anyone replaced the Racor water separator with one with a see-thru bowl? Our boat dosen't have a topping lift. How is it rigged? Great boat.

I'll take a whack
I suspect this is a troll, but aw, what the heck: 1. Cruising speed depends on the wind and point of sail. Hull speed for this boat is 7 knots. 2. I think your engine is a Yanmar 3GMF30. Cruise RPM for that engine is 2500 - 3000 rpm. 3. It's a diesel, don't put any gas in there. I use about 1 tank (30g) per summer. 4. You can remove the play in the steering. Remove the cockpit floor panel just behind the wheel, and you'll see the steering cables connected to the steering quadrant. Loosen the lugs, pull the cables tight, and re-tighten the lugs. A little play is OK. 5. Don't know about the Racor. Don't replace it unless you know how to bleed the air out of the fuel lines. 6. Topping lift goes up from a shackle connected to the end of the boom, over a sheave at the top of the mast next to the main halyard, down through the mast and exits through a square gate (hole) on the port side.

racor filter
the racor filter you want to put in , if it goes in the engine compt. coast guard says no see through plastic in hot compt. ken

Thank you Ken for your response. I was thinking of putting it in the aft cabin where the existing Racor is connected. I like a clear bowl because you can see the condition of the fuel before it becomes a problem.
Hi Paul, Thank you for your response. I don't know what a troll is, but I quess what I don't know won't hurt me. Let me clarify my questions, We have a 2 clyinder 18 HP Yanmar, (2GM30F). The cruising speed question was assumed to be under power. You are correct abot gas, I mean't diesel. I was trying to get a estimate of fuel consumption per hour, because our boat has few engine hours on it and I was trying to get an estimate of how stale the fuel was. We just took the Mack Boring Yanmar class Wed, so we are up on maintenance. Thanks for the info on the topping lift. That's a problem. I may have to improvise. As far as the steering I'll have to take up the cockpit sole. I thought we had rack and pinion steering, which didn't require cables.
Hunter 310 info
Until trading her in on a 2005 H36, I had (and enjoyed) a 1999 H310. The best I could consistenly get under sail with her was 7.4 knots on a beam reach. Pretty good for a 28ft DWL. She's a little tender re initial stability, but has a 38% balast ratio and popped back up easily from 45 degrees on my cockpit inclinometer (why is another story <g>). However, unless you like rails-awash 35 degree heel, just reef at 15 knots of wind. (She'll sail faster with 20-25 degrees of heel, anyway.) I had the stock 2-blade prop, and got 7 knots at 3400 RPM - the "no-more-than-one-hour" speed according to Yanmar. It was a noisy little engine, but would go at 3200 RPM for ever, while only sipping diesel. (The 25 gal tank was good for about 300 miles at 2400 RPM, as I recall. I used to like to keep it revved a bit more, as diesels like, and usually figured 10 miles per gal.) My 310 had no topping lift, and relied on the lazy jacks to perform that function. Since they were only 2-leg lazy jacks, I had to experiment quite a bit on placement of the aft mounting point to get the mainsail to flake well on dropping between the very tight lazy jack lines caused by the weight of the boom. The lower two battens were only leach battens, and tended to catch on the lazy jacks on the way up if you weren't careful. One caveat about 310s, however. While the lazarettes are weather-sealed and latchable, none of the cockpit lockers are, and they feed right into your after cabin. By all means, add weather seals and latches. The rubber draw latches used on the lazarettes are fine for the job, and only cost about $10 each from McMaster Carr. If you get pooped as I did crossing the Merrimac river entrance bar against full ebb after Hurricane Jeanne, you'll be _very_ glad you corrected that down-flooding hazard by adding the seals and latches. If you (easily) add a pair of ST40s on the cockpit coaming for spinnaker use, just going to slighlty longer jib sheets will also allow you to make a great little single-hander of her. I'd better stop before I get too nostalgic about mine. I think you'll like yours, Harv.
