After the 2018 season and taking off about 1 1/2" of the length (chord) I now have tabs about 29 x 13 1/4" with drop fins. The tabs are a parallelogram shape as the transom is not completely 90 to the sides. I could reduce the size a bit more still to be able to push them all the way down...

Yes I did. The first attempt had good results but the chord of the tabs (length) was a bit too large. I can really get the bow down now. The problem was it was too hard to get the tabs down once on plane if I had raised them up too much. Last winter I cut about 1 1/2 off the chord. I can now get...

I had to replace my water pump on my 2007 last year. It was the original Shurflo Variable speed unit and I couldn't find a direct replacement at the time so went with a standard pump. Took it out after 1 day as the pulsating drove me nuts. Looked into installing a accumulator tank but...

The boat has been in the water now for 2 months and have done a variety of trips every weekend and compared the results with previous years fuel burn. I have found that I can run with a little less tab now to find the sweet spot for speed but not much less. When changing the tab position it...

Got the new trim tabs installed yesterday. Going to replace the hinges with the ones with SS pins still. Will launch mid April. Anxious to see the difference these will make.

Juggernaut, I've already ordered new lower hinges with the stainless pins and thanks for the feedback. I will definitely post pics and detailed stats on performance. I find too many threads die after something is implemented and one never knows the end result. I'm not relaunching the boat...

No doubt I'm overthinking it a bit at this point. I was more concerned with retracting them when not moving forward due to the increased weight. I do remember being able to push them down when the boat was out of the water before and they were all the way up. The new ones need about twice as...

An update and a couple of questions for those who have made larger trim tabs. I got the new custom trim tabs back from the SS fabricator. I was lucky that he made me a pair of tabs that included the hinged part so I don't have to deal with bolting, welding or added weight. I ended up with 29"...

Have installed one on every boat I've had. Great to have when at anchor. Tied into the AC panel with a transfer switch through the Genny line. Put the small Inverter control panel in there too. Was a tight fit. Just wish Sea Ray had a dedicated house bank separate from the engine start...

Having a local shop fabricate new custom sized tabs with drop fins now. Will report back when the boat is launched in April on the result. I had good stats on speeds/rpm/fuel burn so it should be easy to see the change.

Your bilge should be dry, especially on a new boat. I had a few leaks on my 44 Sedan Bridge but eventually got fixed. Some where very hard to find. I would start by using a shop vac to get every drop out. Then see if the boat leaks when raining or washing. Then take it out on the water and...

Thanks everyone for your feedback. I'll have a good look at the lower hinges and likely replace as part project. I do understand a formal endorsement of an aftermarket alteration cannot be made. I am going today to make some templates and confirm angles. I will have to also do a...

Tabman, Should my goal be to have the drop fins parallel to the centreline of the boat or sides of hull? I don't want to be adding any drag or sideways pressure to them.

Tabman, Is A1114 the best one to order then that comes with the SS pin? My boat is a 2007 so I don't know if it has the SS pin. I'm going there today so I should be able to see. Otherwise it's A1113 I guess. Juggernaut, My current 12x24 tabs are perfectly rectangular. Are you saying your...

I too was looking to keep this simple but after another visit today I found a few issues after measuring. The good news was I found a fabricator that can either make a larger tab to bolt to my existing one with drop fins or a new one with the hinge in it. First I measured above the prop...

Tabman. I'll see if I can make up a scale mock up with the main dimensions and see how the fit is. On the topic of the retention device when are the tabs most susceptible to movement from the boat rocking around when not in motion? When they are fully extended downward or fully up or in the...

Tabman, Thanks for all your info so far. Went to the boat again today to investigate further. My current 12x24 tabs have the short cylinder as I think was mentioned earlier. The top edge of the cylinder where mounted on the transom is 8 1/4" above the top of the trim plane (about 8 3/4"...

Gofirstclass. Thanks for the mockup. In the photo of the starboard tab I have 2" to the left to the prop pocket and 2" to the right before the curve starts to happen that goes to the chine. So if I want to widen and leave the hydraulic cylinder alone and centred I can do a 28" wide tab max...

Tom, thanks for your feedback. I have considered that. I could possibly fit 12x12 ones here but would have to be a short cylinder as the one I have on the existing tabs (it has 3 rings on it) due to the shape of the hull above the area. I will have another look in the engine room as this...

Juggernaut, I had seen your post earlier and I am leaning towards a similar modification as I am limited with space. Did you every keep track of various speed/rpm data before and after the mod? I think if I didn't have the underwater light in the way I could have squeezed in a 12x30 with a...
