and that's at 1850-1900 rpms, those figures I posted......1950 will get you 27.5 knots usually with a clean bottom and no dinghy on the bow and 60...
Because the engines are rated at 2300 rpms/100% throttle/ 100% load. So the boat is under propped a little and underloaded. Which is what MAN...
No, you cannot weld cast iron. I've seen people drill and tap and screw a plate over a hole in Detroit Diesels before......I would NEVER do this....
Those are all perfect numbers. I like to see 2350 rpms on Man's even when they're rated at 2300.
As a whole no. Very very few 50's built with Cat's. BUT, the MAN's are an excellent fit. 26 knot cruise at 55 gph, they're smooth and quiet and...
I'd step up to a 50' Post with Man's. It's a far superior boat in every aspect and a heck of a lot more room.
I run a Hampton that size and it will handle it.
I used to run a 70' seajet as well and also a few 68 plus'. The seajet is a very good sea boat. A bit wet in a sea, but had her in 8-10's off of...
With the breaker off, I think it backfeeds the freshwater system and with the pump shut off you can use it as dockwise water.
They would be my second choice (1st in most applications). But the OP has a 45' speedboat, so the higher revving Yanmars generally are a better...
Yeah well, you can get Yanmar parts and service everywhere and they have a high power to weight ratio and are high rpm motors which is a perfect...
Then call a mechanic that works on generators. The amount of time and money I see people throw at a problem on boats trying to fix something...
I'd just have someone from Lauderdale go there.....Florida Yacht Surveyors or Matt Jones are both very good and travel.
I'd go with Yanmar's in that application.
Most boats didn't have a galvanic isolator in 1988. They're easy to install and generally I install them right after where the shorepower comes...
The main thing you look at is what they look like when they're 10 years old. Searays look nearly new inside AND out if relatively taken care of....
The 2 companies are both owned by Brunswick.....they are not the same company and Meridian is definitely built to a lesser standard than searay....
Keep in mind Seakeeper does an excellent job at 10 knots or less or drifting/anchored. BUT when running fast they probably only offer a 20% roll...
200 hours in 30 years? That's even worse for it. The sticker with the spec number is usually on the top or side of the black electronics box with...
I wouldn't touch gas in that size range. Also the searay is much better quality and a much better sea boat than the Meridian.....
