Did you know in the 1800's, some Royal Navy ships had the floors of their sick berths painted red
to make the blood stains easier to clean up.

Here we go.

MV Summer School does 2400+ miles on the Great Lakes this summer.


We left from Brewerton, NY, (on the Erie Canal) the 10th of June, we have our boat there @ Winter Harbor, tucked away in indoor heated storage. We went across Lake Ontario in two days and meet friends at Niagara on the Lake, a spectacular spot, we went to the Shaw festival which runs all summer, and rode the shoot over rapids boats in the Niagara river, very cool.

Next was the Welland Canal which connects Lake Ontario to Lake Erie. Across Erie to Sandusky, Cedar Point, the 4 kids wanted roller coasters and there are more of them here than anywhere in the world. Then north past my most favorite house in the world.

Up to Detroit and then Lake St. Clair to the Gross Point Yacht Club for 2 days. Moving north up to Lake Hurons west shore and crossing to Drumond Island. Then up the St. Marys River to Lake Superior, Its mighty cold (38 degree water) and foggy up on Superior even in the summer. Then back across Superior and across the North Channel to the Great Lakes Cruising Clubs Rendezvous in Killarney, CN from July 10th to the 15th. Across Georgian Bay, then a slow easy passage via the Trent Severn Waterway, (240 miles) down to Lake Ontario again, and back to Winter Harbor in New York by August 1.

Here's our personal boating website: http://www.maxumowners.org/MVSS.html

Having done the great loop and over 13,000 miles on the ICW and Great Lakes, in our Maxum 4600 SCB we decided to again leave our Maxum at Winter Harbor in Brewerton NY at the end of this year.

Are your Diesels Slowing Down?
You may have a restriction in your intercooler:

I was loosing RPM on the top end and was intermittently using more oil in one engine. I was at a loss for what it might be, except for a major bill, it is a boat. I talked to three sources and they all agreed that the intercooler needed to be checked for an obstruction. There are two ways to do this, one a visual inspection, and two (the better way) is to verify by a pressure gauge that there is no more than 3 psi difference between the intake and outlet of the intercooler. Mine were obviously clogged, and starving the engine for air when operating over 2200 rpm. So much so that they were sucking oil down the valve stems. That were the excessive oil use came from. A quick check is to make sure the engine can do it rated no load rpm, for the 450C that 3000 rpm when warm, in neutral. Mine could not before cleaning. Heres a photo of the inlet intake pipe of the intercooler to show what the clogged internal fins looks like. Jim Clausen

4600 owners, shower access panel information.

This is from Vern, one of our 4600 owners from Michigan. Vern had a leak in the guest shower of his 4600, he found out from Maxum that the backing panel in the master stateroom was removable, it's installed with Velcro! Removing the panel allows access to the plumbing.

Here are some photos of Dale & Michele Grooters, 4100 SCA taken at the Great Lakes Cruising Clubs Rendezvous.
This was so nicely done the factory would be in awe.

And you though you were having a bad day:

This is a 3 1/2" SS shaft, yes, the shaft is really twisted.
The boat was run over a rock outcropping in Montreal.

The Boat hit so hard it pulled the 12 cylinder MAN engine back one foot.

The second propeller.

This is how you replace the engines and running gear. You cut the side out with a gas powered saw.
Then use a huge fork lift, the port fuel tank was the first piece to come out.
There no way to get up through the top.

Trim Tabs,
why ours are better than most:

Note that the ends of the tabs are angled down 90 degrees, and the tabs are braced at the cylinder connection points.

The 90 degree angling down of the tab, acts to increase the force of the tab,
without increasing the tabs length. Not all tabs are made this way.
