The marine dipstick should be a long one in a tube on the starbourd side. An industrial one would be a short one low down on the port side. Is the engine tilted down towards the stern at a steep angle. Is the boat listing heavily to port if the dipsticks on the starboard side and visa versa if on the port side when you dip the oil. Is there a remote oil cooler or extra remote oil filters piped to the engine. Are you wiping the dipstick first before dipping the oil after running the engine. How much oil did you drain out at first. Is it the correct dipstick, there are 2 or 3 different ones for those engines, Edited April 24, 2019 by bizzard Link to comment Share on other sites More sharing options...

I can't see any additional remote oil coolers. so the 9 1/2 pts should be correct. And the angle of the engine looks reasonable.. Did you note how much old oil you draned out in the first place, that is important. If the engine is reasonably level when you dip the oil and you need to add a further 5 litres !!! to get it on the full mark either your not pushing the dipstick fully down when checking the level or its the wrong dipstick ''Too short''.

Roxylass Posted April 25, 2019 Author Report Share Posted April 25, 2019 Yes it was 91/2that came out I will take five litre back out Give it a small trip and see what the oil gauge is reading Link to comment Share on other sites More sharing options...

Careful with going for a trip with incorrect oil levels though - 5 pints too much or too little is a long way out. Link to comment Share on other sites More sharing options...
roland elsdon Posted April 25, 2019 Report Share Posted April 25, 2019 You talk about a dipstick and an oil gauge. you talk of an oil gauge dropping. i assuming you mean oil pressure not level. it is of course normal for the pressure to drop as the engine gets hot but not the level. does it share oil with the gearbox and did you drain that?

Roxylass Posted April 25, 2019 Author Report Share Posted April 25, 2019 Yes i do mean oil pressure Try and get a pic up when I get home from work may have bent the dipstick tube When fitting a new cylinder head It is the original dipstick Link to comment Share on other sites More sharing options...

Arthur Marshall Posted April 25, 2019 Report Share Posted April 25, 2019 (edited) My SR2 takes just over 5 litres, which is what the manual says (9 1/2 pints). The dipstick is a bit odd in that it shows two levels as usual, min and max, but there seems to be only about half a litre between them. Nothing at all shows on the stick until there's about four litres in. I can't remember the number on the top - will check when next i go to the boat. ETA I have a vague memory of being told that the SR2 dipstick should have three marks on it rather than two, and I don't think the number on the top related to anything in the manual when i looked it up, but as it's got the right amount of oil in at the full level I stopped worrying about it some years ago.

bizzard Posted April 25, 2019 Report Share Posted April 25, 2019 A dipstick can be made quite simply for these engines. I've had to make a couple in the past including for my own ST2. Obtain a length of 1/8'' steel gas welding rod, they come in 1 yd lengths or 1 m lengths these days from a good garage or a welder. Also a collar to act as a top stop with a side securing screw to slip over the rod,''I used small Meccano pulley wheel. Make sure there is the correct 9.1/2 pts of oil in the engine to begin with. Poke the rod down the tube until it hits bottom, slip the collar on over the top. Withdraw rod about 1'' and tighten collar stop to retain that position. Withdraw dipstick rod, wipe it and then re-insert it until collar hits the tube top. Withdraw it and mark the max oil level on the rod with a couple of cross wise strokes of a Junior hacksaw. A second mark about 1/2'' below your max mark can also be marked with the saw. You can bend a loop or an L shape at the top of the rod as a finger pull. Cut off excess uneaded rod. And that's it, one new Dipstick. The rod will easily adapt itself to the curve of the tube after a couple of uses and retain it. Link to comment Share on other sites More sharing options...
bizzard Posted April 25, 2019 Report Share Posted April 25, 2019 (edited) As described above. Made in 2005 for my engine. As you can see I cut three marks on mine but you only need the one or two. And I did file a flat on the end where the marks are but you don't need to. Edited April 25, 2019 by bizzard 1 Link to comment Share on other sites More sharing options...
Roxylass Posted April 27, 2019 Author Report Share Posted April 27, 2019 Here’s a couple of pictures of the dipstick you can clearly see the max mark the one with my thumb is the oil level at the moment pump sucked out a good ten litres took the sump drain nut out sits just behind the starter on the bottom of the sump only drips coming out so I know it’s empty going down tomorrow morning with a pint bottle make sure it only gets nine and a half pints hope it shows up on the dipstick Link to comment Share on other sites More sharing options...

RLWP Posted April 27, 2019 Report Share Posted April 27, 2019 On the end of the brass handle is a number that identifies the dipstick. I have a table that identifies the part number for each dipstick based on that number, and with a parts list I can check you have the right one Richard Link to comment Share on other sites More sharing options...
Roxylass Posted April 27, 2019 Author Report Share Posted April 27, 2019 Ok Richard I will get the dipstick up and take a photo of it Link to comment Share on other sites More sharing options...
Arthur Marshall Posted April 27, 2019 Report Share Posted April 27, 2019 (edited) The max mark is more or less where mine is, though mine has another line about 3mm from the bottom.. I've had oil levels up to where your thumb is when I was getting diesel mixed in. But it's only about a litre at most from when it appears on my stick at all before it hits the max line.

Roxylass Posted April 27, 2019 Author Report Share Posted April 27, 2019 Don’t know if this helps any or not but when I replaced the oil I poured it down through the rocker covers i now know that is not the correct procedure Link to comment Share on other sites More sharing options...

Most boat engines, you don't get the chance to use the crankcase filler because of all the other stuff in the way And not all engines have a crankcase filler anyway Richard Link to comment Share on other sites More sharing options...
