Penta engine- What is it?
First off, apologies as this may be in the wrong part of the forum, but being redblock based and I had redblocks before defecting to d5, I thought the best place would be to ask here.
Looking at a Fishing boat. Fitted with a 2.0 penta carburetted engine. Am I right to assume this is a B200 with a carburettor and a different camshaft? Reason I want to know is that it has supposedly been "Overheated" and there is top end noise. Bottom end is fine apparently. If there is a top end damage, could I just bung a decent 531 head on and make sure the camshaft is fine? Or should/could I haul it out, and drop a b230fk in with a standalone management system? |

I think a bit more research may be required here? |
Volvo penta engines of that era came in many types over the years.
If the engine is an aq115, then it is akin to a b20 from an Amazon or similar era car. If it is an aq120/aq125, then it is akin to a b21/b23 from 240s and the like, If it is an aq131/aq151/aq171 then it is b230 derived. I have never known of a b200 derived penta- only b20. Here is what an aq115 looks like: https://nordicarmarine.com/en/produc...b20-penta.html |
Well, It's a start. Thanks so far. It definitely doesnt look like what was pictured from nordicar.
It MAY be a b20, picture suggests it, But I have only ever dealt with 700 and 900 engines, never the 200/amazon. The seller cant give me specifics unfortunately. I believe its a B20. The link is here https://www.ebay.co.uk/itm/154995426...fec%7Ciid%3A14 I remember searching for cams a long time ago, before I transistioned to diesel, d24tic's etc, having owned a higher performance b230fk with a K cam IIRC. I sold the cam because it was way too revvy. Anyway - Penta I know has a different cam, not sure on head though. I just thought I would run it past a few of the redblockers before I continue to bid. If it was a case of "new" head, and as long as the cam hasn't stuffed its bearings/tappets, I can probably save it. Or just chuck an FK at it. I've seen a few marinised escort diesel engines, helped remarinise them with the correct kit... I think a visit may be in order. If I win, those decals broadcasting its a penta are coming off, And Draco? hmm... really? |

A friend had a launch with 2 x B30 3 litre 6 cylinder 175 bhp engines side by side unique to this version was 3 stromberg carburettors per engine , they had the B30E camshaft. |
Hi
I would agree B21 the easy way to goo would be B 230 swap the bits over and rejet the carb hole job about 1 day I think the carb will be solix in my view yuck but good for flat out power |
This might be worth a read and suggests it's definitely not a 2.0L, more likely 2.1L (2127cc) or 2.3(2316cc) :
https://en.wikipedia.org/wiki/Volvo_...ne#Volvo_Penta Remember also that the whole idea of it is the simplicity - no complicated ECUs etc, just a basic carb so retrofitting a B230FK/FT would mean fitting the ECU, EZK, loom and so on just to get the engine to run. If you wanted more power, look for a later Penta engine running on carbs, the AQ151 is about 150bhp and still simple with no ECUs etc. |

hi
I dont understand if you swap all the penta bits over why would you need the wiring and the ecu etc |
