DAMN !!!!! I'll take Andrea

That is a great one Paul. He thought his F32 burned fuel - wait till he fills up that 300 gallon tank and watches it burn 25GPH at 18kts. Not exactly warp speed but pretty good on a tri-cabin.

What was her name? Can't remember - but she'd be perfect at the helm .. barking orders!

or just barking....

That's why you have to learn to run at impulse speed . 8 knots and explore the vast ches. bay.

the actress was persis khambatta and she played LT. ILEA from delta4. although i would NOT mind a 7of9 standing on the deck as we leave the marina.
okay, as for 'warp speed', my mechanic told me that above a certain rpm with these engines, i will be operating on 4 barrels of the carburetor. so, i guess i will be using 'impulse', or 2 barrels at a lower rpm. since these engines are sort of 'new', 1998, i assume they are a little more fuel efficient than the one's on my f-32.

another milestone was reached yesterday when i FINALLY received from my broker, the official ''ACCEPTANCE OF YACHT AND SURVEY OFFSET CREDIT''. one step closer to closing. as for calling phil 'number one', (sometimes he acts like a major number 2--get it?) no no no. but, i have actually said to him, 'take her out' and 'engage throttles etc....' even though her name will be ENTERPRISE, she is hardly a product of the 23rd century (may this planet actually see the 23rd century).

i fired up the engines yesterday for phil. it was his first time listening to her and the odd feeling of the underwater exhaust. one thing that totally freaked him out was the 'rumble effect' from under the boat as the exhaust gasses were bubbling from underneath. even though there is an idle 'side exhaust' overflow function, there is quite a bit of rumble felt through the boat from underneath. learning curve i guess. now, since this is my first experience with underwater exhaust, is it normal to feel the rumble from under the boat? if anyone out there has this, especially you post 1976 tri cabin owners, let me know.

Normal

It took me a dozen cruises to get used to it. There is a noticeable vibration from the time I put her into gear until past 1300 rpm. My mufflers look the air bag shocks on a tractor-trailer. You can actualy push down on the top of them and they will slightly go up and down.
During the seatrial I thought the engines were a little out of tune because of the vibration but I told the widow I would tune them when I got her home.
Definately have to keep an eye out for barnacles in the "pan flute" since it would impede flow of exhaust.

Looks like you have the engines in the salon bilge like mine. I like that since I can leave the top sliding cabin door open while underway and listen to the engines purr. Mine don't hit "Warp" until 3100 rpm under most loads. I'll be installing fuel flow meters over the winter. Something you might want to consider since they can give you a lot of peace of mind.

Very normal and sounds kind of neat really.

Mine kick into the 4bbl at about 3,000 RPM - I never go there since I am never in a hurry to get anywhere when on the boat. 2,900RPM and 18kts is just fine with me. As she burns off fuel I have to keep bumping the RPM down a little to keep it at 2,900RPM. I burn 25GPH at that setting.

Tim...... do you have fuel flow meters ?

No I don't, I just keep very close track of fuel consumption - a throwback to my flying days I guess.

What size engines do guys have in your tri's. Mine has has 454's and burns 20 gph at 14 knots and 21,000 lbs . Burn rate is est. off usage.

I have the twin Merc 255's. As I said mine do 18kts @ 2,900RPM and burns 25GPH. I established my burn rate during a 680 mile trip to bring her home when I first bought her. My owner's manual lists performance numbers for all engine packages offered that year and are very accurate.
