My rpm range is between 3800 and 4100 at cruise depending on what speed I would like to run at.

I have a single 300 g1 on an 86 sailfish Hull and it's a great combination. Boat tops out at 42 mph and cruises at 25 mph doing roughly 2.1 mpg. A single will make a huge difference with the scuppers. I no longer worry about the scuppers staying submerged. I was told the same thing that the...

The only idea I can come up with is to actually cut out the drain area in a larger diameter and make a flange that can be screwed and glued back down with the drain in it. Not sure how well this will work, but I figure it's worth a shot. It's either that or I will have to pay a shop to do...

So this past weekend I had to dislocate almost every joint in my arm to replace the overboards for the fish boxes and live Wells. For anyone out there that has a late 80's sailfish, how do you replace the drain in the bottom of the stbd fish box behind the captains seat? I cannot fathom how you...

when you are at cruise speed do you trim the motors up at all or leave them fully trimmed down? what i have found that works best for my set up which is slightly different as i have a single 300hp E-Tec. I fully retract the tabs once i'm on a plane and then slowly trim the engine up until the...

I have the exact same hull and year. what engine set up are you running and how do you usually trim the engine(s). I have had to play with my set up as well in order to remedy the bow steer issue.

Re: repowering a 1983 grady 255 sailfish with a 300 hp suzuk what year were the 175's you had on the back? I had a set of late 80's Johnson 175's on the back of my 255 sailfish and changed over to a single 300 E-Tec. I love the new configuration and the single engine has more than enough power...

The seafarer is a really nice riding boat with the Sea V 2 hull i have ridden on a few friends boats and it is typically a nice ride. i own an 87 255 sailfish with a single 300 etec and love the boat. I boat mainly in the eastern long island sound/ fishers island area and the boat performs...

i could be wrong but when i was looking at the HO's you could only get them up to a 25", so probably wouldnt be able to use one for a single application. certainly would be nice to have one though, if only they would make a 30" leg in the graphite color

you would probably be happier with a 250 as it will handle the boat better when its loaded down. plus in the long run the engine will not be worked as hard to accomplish the same task. i went through the same process you are going through and in the end i decided on a single 300 for a 255...

the odds of the camshaft failing in such a position that you would read 0 psi on any cylinders for that bank due to the valves being partially open is very little because of the firing order of a V6 engine. if any oil passages were blocked to that side of the block it would be very easy to...

yes but that can be due to ring failure for the pistons on that side due to the oil pump failing. like i said before as long as none of the bearings were damaged for crankshaft, camshafts, connecting rods, etc then youll be fine. you said the oil looked ok so if there wasnt any metal particulate...

if the temperature was ok and the high temp alarm didnt sound that is a good sign which should mean the engine did not get too hot and you caught it fast enough.

ok then IMHO the problem most likely with the engine is that due to the failure of the oil pump the cylinders on the port side of the engine have overheated to the point of damaging the piston rings and will need to be re honed and new rings installed. you will also have to figure out why the...

assuming that the mechanic was able to roll the engine over freely to take the compression #'s that is a good sign which means the power head should be repairable. from what you have said the oil pump seems to have failed but the only way to know this for sure is to check the pressure using...

IF it is a four stroke the first thing you would have to check is pull the plugs and take a peak in the cylinders to see if there is any discoloration of the cylinder walls and if the honing is still visible. when you say that the three cylinders had no compression do you mean zero or that is...

Could you provide a little more information on the engines such as 2 stroke or 4 stroke any other issues you may have had with them. hard to give you an honest opinion without all the facts. sorry for your engine troubles...we have all been down this road before.

so i finally managed to get the boat in the water after almost 11 months of work and repairs. took the boat out for the first few runs with the family and apsolutlely love the 300 Etec with the electronic throttle. my question is does anyone have comparable figures to the rough couple of tests...

finally got the boat launched after a winter of replacing the transom, main fuel tank, removing the aft fuel tank permanently, installing new controls and engine.
